Generalization of Relational Matching to Sample in Children: A Direct Replication

The ability of preschool age children to perform generalized relational matching to sample tasks with and without an overt mediating stimulus was examined. This experiment was a direct replication of a study by Lowenkron (1984) and examined a behavioral model relevant to complex human behavior that he later came to call joint control. Children were trained to code two-dimensional stimuli with the help of a handheld mediating stimulus. They were later tested for generalization of relational matching to sample with and without the mediating stimulus. Results indicated high levels of generalized matching to sample with the mediating stimulus and lower levels without. Findings also indicated that generalization was somewhat stronger with symmetrical shapes than with asymmetrical. Results are discussed in terms of a radical behavioral interpretation of complex human behavior.     

Betting on Illusory Patterns: Probability Matching in Habitual Gamblers

Why do people gamble? A large body of research suggests that cognitive distortions play an important role in pathological gambling. Many of these distortions are specific cases of a more general misperception of randomness, specifically of an illusory perception of patterns in random sequences. In this article, we provide further evidence for the assumption that gamblers are particularly prone to perceiving illusory patterns. In particular, we compared habitual gamblers to a matched sample of community members with regard to how much they exhibit the choice anomaly ‘probability matching’. Probability matching describes the tendency to match response proportions to outcome probabilities when predicting binary outcomes. It leads to a lower expected accuracy than the maximizing strategy of predicting the most likely event on each trial. Previous research has shown that an illusory perception of patterns in random sequences fuels probability matching. So does impulsivity, which is also reported to be higher in gamblers. We therefore hypothesized that gamblers will exhibit more probability matching than non-gamblers, which was confirmed in a controlled laboratory experiment. Additionally, gamblers scored much lower than community members on the cognitive reflection task, which indicates higher impulsivity. This difference could account for the difference in probability matching between the samples. These results suggest that gamblers are more willing to bet impulsively on perceived illusory patterns.     

Peers' influence and African-American youth in public housing

Drawing from problem behavior theory (PBT), this study investigates whether the relationship between exposure to delinquent peers and delinquent behavior is moderated by peer influences as well as by generalized self-efficacy and an adolescent's attitudes toward deviance. We also explore how gender may influence these relationships. A sample of 401 African-American adolescents living in public housing developments in two large US cities was recruited for this investigation. The preliminary analyses included t-test and bivariate correlations, while our primary analysis included hierarchical regression analysis. The regression analysis included two-way and three-way interaction terms to assess the moderating effects of peer influences, generalized self-efficacy, and attitudes toward deviance as well as gender, respectively. Results indicate that the effects of exposure to delinquent peers depend on peers' influence over adolescents and other factors. Findings provide partial support for PBT and suggest that the relationship between exposure to delinquent peers and delinquent behavior, with regard to minority youth living in urban public housing, merits further investigation. Results have the potential to guide preventative interventions targeting African-American youth living in urban public housing and also inform future inquiries into the lives of such youth.     

The effect of joint control training on the acquisition and durability of a sequencing task

Gutierrez (2006) experimentally demonstrated the effects of joint control and particularly the role of response mediation in the sequencing behavior of adults using an unfamiliar language. The purpose of the current study was to replicate and extend the procedures used by Gutierrez by comparing the effects of joint control training with the effects of a prompt-and-fade procedure on the acquisition of a sequencing task. The effects of each procedure on delayed sequencing behavior were also tested. Ten undergraduate students participated in 2 experiments. The results indicated that all participants acquired the sequencing response in fewer trials and maintained accurate delayed responding when the component responses necessary for joint control were directly taught. Finally, when the self-echoic mediation component was blocked, accurate responding deteriorated in 8 of 10 participants.     

Beyond Transitions: Applying Optimal Matching Analysis to Life Course Research

Life course researchers have increasingly explored optimal matching analysis (OMA) as a tool for the analysis of sequences, such as sections of people’s status biographies. OMA is usually employed in combination with cluster analysis (CA) to create classifications of sequences. In this article, we introduce an analytic strategy that allows assessing the classification’s internal validity. Using ideal typical sequence representations, we test different cluster algorithms and are able to optimise the fit to the data. An application analyses economic activity sequences collected for two British birth cohorts born in 1958 and 1970, investigating historical changes in passages to adulthood. The results suggest that passages into adulthood have become more diverse since the 1970s. The analytic strategy produced a classification with better fit than straightforward CA.     

Rhythm in Mother‐Infant Interactions

Rhythmic behavior and the association of vocal rhythmic behavior with language development were studied in a sample of 30 mother‐infant dyads. Dyads were observed in 2 contexts (1 involved sharing pictures and the other sharing musical toys) when infants were 18 and 24 months of age. Vocal rhythmic behavior was seen in both contexts, and in both contexts mothers matched their infant's vocal rhythmic behavior at greater than chance rates. Greater matching tended to be associated with higher language scores whereas, counter to prediction, higher rates of maternal vocal rhythmic behavior tended to be associated with lower language scores. At 24 months of age, mother‐daughter dyads showed more matching than mother‐son dyads. These results suggest that differences in maternal production of vocal rhythmic behavior may foster different language learning strategies.     

PM effect size estimation for mediation analysis: a cautionary note,alternate strategy,and real data illustration

As research on mediation has grown, so too has interest in identifying ways to assess the size of indirect effects in a mediation analysis. One such estimate – the ratio of the indirect effect to the total effect (P_M) – was tested in a sample of 21,297 children from the Early Childhood Developmental Study. Results showed that the two independent variables – low self-control and externalizing behavior – correlated equally well with a common mediator (mathematical thinking). Moreover, the two pathways shared the same mediator and dependent variable (subsequent externalizing behavior). Despite this, P_M was three times larger in the self-control-initiated pathway than in the externalizing-initiated pathway, based on a stronger correlation between prior and subsequent externalizing behavior than between low self-control and externalizing behavior. The comparison pathways approach, where pathways mediated by mathematical reasoning are contrasted with pathways mediated by a control variable (general knowledge), is offered as an alternative to effect size measurement in mediation research.     

If you feed them, will they come? The use of social marketing to increase interest in attending a college alcohol program

The authors used social marketing to design and test advertisement components aimed at increasing students' interest in attending an alcohol program focused on reaching students who drink heavily, although the authors offered no such program. Participants were undergraduate students in introductory psychology courses (N = 551). Questionnaires included measures assessing demographic information, alcohol use and negative consequences, and interest in attending an alcohol program in response to exposure to 1 of 12 systematically varied advertisements. The authors found that approximately 20% of participants across all ad types indicated some level of interest in attending the alcohol program. Students who use alcohol reported more interest in attending when an informational message was used. Of the participants offered food, 41.9% indicated the food offered in the advertisement impacted their interest in attending. Results suggest market segmentation plays a role in developing effective advertisements to recruit different groups of students based on their reported drinking behavior.     

Criminal Behavior Associated with Pathological Gambling

The influence of addictive gambling behavior on criminal behavior was examined in this study. A sample of pathological gamblers from in- and outpatient treatment centers and self-help groups (n = 300) and a sample of high and low frequency gamblers from the general population and army (n = 274) completed a comprehensive questionnaire which assessed social attachment, personality, pathological gambling and criminal behavior variables. The causal analysis of a Lisrel Model leads to the following results: addictive gambling behavior is an important criminogenic factor. This predisposing factor alone cannot sufficiently explain criminal behavior associated with pathological gambling. Personality variables also directly influence the intensity of criminal behavior. Social attachment variables have only an indirect effect. As far as property offenses are concerned, it was found that the direct causal effect of addiction behavior is greater than that of personality.     

Getting it together: Social and institutional obstacles to getting off the streets

Avoiding macrostructural or individualistic explanations as to why homeless individuals cannot get off the streets, this paper examines the social structure of street life as it impinges on a sample of homeless persons' chances of obtaining nonshelter housing. Specifically, by interviewing 42 homeless individuals about a housing grant offered by New York State and the possibility of obtaining shared housing arrangements with such a grant, this study documents possible ways in which the social relations homeless people have with institutions and each other may dash potential efforts to obtain nonshelter housing. The research finds that distrust of the homeless among landlords and a high level of contingency with respect to welfare cases interact with distrustful personal relations among the sample of homeless themselves to reduce the likelihood of successful utilization of the housing grant. Due to sample limitations, findings from this study cannot be generalized to all homeless; nonetheless they offer insight into a dynamic which may be similar to those at work among other homeless sub-populations as well. An earlier version of this paper was presented at a regular session of the American Sociological Association Annual Meeting on August 9, 1994.     

Response Results of Lottery Buyer Behavior Surveys: In-Home vs. Point-of-Purchase Interviews

This paper reports the response results of surveys on lotterypurchasing behavior. Data are based on answers generated fromtwo probability samples: a national, random sample of 1,646households (in-home survey) and a point-of-purchase sample of520 respondents. Results show that answers to the point-of-purchasesurvey were more accurate at half the cost of in-home interviews.The surveys were undertaken in Israel, but have implicationsfor those wishing to sample lottery purchasers in other countries.     

Games of school choice under the Boston mechanism with general priority structures

The Boston mechanism is a centralized student assignment mechanism used in many school districts in the US. We investigate strategic behavior of students under the Boston mechanism when schools may have complex priority structures. We show that a stable matching is supported as an outcome of a Nash equilibrium under a general environment. We further show that any outcome of a Nash equilibrium is a stable matching when the school priorities are substitutable.     

Group Therapy for Parents of Mentally Retarded Children*

Parents of mentally retarded children face many special stresses. They have traditionally been offered information about their children but little opportunity to explore their own needs and difficulties. Such an opportunity was offered to parents, as couples, in group settings. The leaders concluded that the most effective approach was an eclectic one including Rogerian reflection, Freudian interpretation, Ellis' reality therapy, Gestalt techniques, and learning theory-based behavior modification. Most parents proved to be compassionate and insightful group members with a great deal to offer each other.     

The Role of Joint Control in the Manded Selection Responses of Both Vocal and Non-vocal Children with Autism

In the present study, joint-control training was applied when teaching manded selection responses to children with autism. Four vocal children with autism participated in the first experiment, two males (ages seven and eight) and two females (ages seven and nine). The results showed that it was only after object-word naming was trained under joint control that the symmetrical performance of manded selection responses appeared with no additional training. Four non-vocal children with autism participated in the second experiment, two males (ages six and seven), and two females (ages twelve and thirteen). These results also showed that it was only after the joint tact/self-mimetic/sequelic control training that the symmetrical performance of manded selection responses appeared with no additional training.     

Hong Kong adolescents' use of MSN vs. ICQ for developing friendships online: considering media richness and presentational control

Grounded in the concepts of media richness and presentational control, two popular, free instant messengers (IMs), ICQ and MSN, were compared through a snowball sample of 180 Hong Kong adolescents who completed a questionnaire anonymously. Respondents using both MSN and ICQ perceived MSN as a richer IM that offered greater control than ICQ. MSN's greater richness and control, relative to ICQ's, resulted in teenage users' spending more time and discussing various topics more frequently on MSN than on ICQ. Relative factors such as richness and control have led to better friendship quality on MSN than ICQ, but have not introduced differences in the number of friendships. Media richness and presentational control appear to be viable concepts in explaining the behavior governing the usage of IMs.     

Hypnotic analysis of the recognition of a sex symbol

Evolutionary and environmental theories of erotic response, sometimes termed “sociobiology” and “socialization” theories, respectively, are compared on the basis of the structural strengths and weaknesses of each approach. More space is devoted to the evolutionary approach because sociobiologists have offered a more detailed theoretical analysis, thereby allowing for greater criticism and, also, because these theories are not directly testable. Examination of socialization theories is more straightforward. The review focuses on how the presence of an effect favors either an environmental or an evolutionary interpretation. This review is concerned with the basic methodology and the sharpening of theoretical concepts which may be used to develop more complex accounts of erotic response. The term “erotic response” refers to sexual arousal and/or attraction. A sequel to this article will examine the utility of these approaches within specific content domains     

Evaluating the effectiveness of the Massachusetts workforce development system using no-shows as a nonexperimental comparison group

This article examines the effect of the Massachusetts workforce development system on the earnings of disadvantaged adults using nonexperimental data from the late 1990s. The authors construct a comparison sample for program participants using individuals who apply for and are offered services yet do not participate in a training program. They present a series of difference-in-difference estimates that make several alternative efforts to correct for selectivity bias, including econometric models that regression adjust for observable characteristics and fixed-effect models that adjust for time-invariant person effects. They also employ probabilistic matching techniques to more finely align the treatment and comparison samples. On average, program participants experienced 20% increases in annual earnings 1 year postintervention and 25% increases after 2 years. The authors uncover considerable heterogeneity in these effects, suggesting that the most difficult to serve and the most job ready benefit the least.     

The place of sociology in a drug education curriculum

This article gives consideration to the part a sociological perspective can play in a drug education curriculum. Sociology's study of human behavior from the context of various social groupings is considered appropriate to any understanding of drugs and drug use, as are a number of substantive areas common to the discipline. The sociological perspective is examined from the broad foci of structure and process, and with each focus examples of a sociological approach to drug use is offered. The common concerns of these approaches, as well as their points of divergence, are discussed. A sample outline of a course in "Drugs and Society" is also presented, suggesting the ways in which the sociological issues discussed could provide an orientation to the study of drug use in a social context.     

What Is Ecological Validity? A Dimensional Analysis

Ecological validity has typically been taken to refer to whether or not one can generalize from observed behavior in the laboratory to natural behavior in the world. Although common in current discussions of research, the idea of ecological validity has a long history in psychological thought. A brief historical examination of this idea reveals that concerns with ecological validity are evident in multiple dimensions of experimental work, including the nature of the experimental setting, the stimuli under investigation, and the observer's response employed as the measure. One problem with this multidimensionality, however, is that no explicit criteria have been offered for applying this concept to an evaluation of research. One consequence of this problem is that concerns with ecological validity can be raised in most experimental situations. This article includes a discussion of some demands of ecological validity and the nature of these different dimensions, as well as a critical evaluation of research on the development of mobility with respect to these constraints.     

Trends in Evolutionary Explanations for Human Male Same-Sex Eroticism: A Commentary on Riegel (2011)

Objectives: Riegel (2011) argued there is a moral panic surrounding the issue of male transgenerational eros in the West. In response, he offered a variety of contrasting perspectives, one being that such eros has an evolutionary basis. The present article offers commentary. Methods: I supplement his hypothesis with a review of seven related evolutionary hypotheses and then compare/contrast all eight. Results: All these hypotheses constitute a work in progress, which Riegel adds to by properly restricting evidence (e.g., cross-cultural) to male homoerotic type (i.e., transgenerational). Conclusions: Riegel contributes to addressing the moral panic, and his evidence-type matching, which is part of a new trend in this area, promises to improve validity.
