Erratum to: Token Reinforcement of Verbal Responses Controlled by Temporally Removed Verbal Stimuli

In the present study we examined the effects of token reinforcement on the convergent control of immediate and temporally removed verbal stimuli over the verbal behavior of three school-age children with autism who showed specific deficits in intraverbal responding. Throughout the study, participants were systematically introduced to a series of visitors to a university-based autism center, and subsequently probed for information about the visitor they had most recently met. Results show that contingent token reinforcement was effective at establishing control by temporally removed verbal stimuli.     

Assessment of Distraction From Erotic Stimuli by Nonerotic Interference

Distraction from erotic cues during sexual encounters is a major contributor to sexual difficulties in men and women. Being able to assess distraction in studies of sexual arousal will help clarify underlying contributions to sexual problems. The current study aimed to identify the most accurate assessment of distraction from erotic cues in healthy men (n = 29) and women (n = 38). Participants were assigned to a no distraction, low distraction, or high distraction condition. Distraction was induced using an auditory distraction task presented during the viewing of an erotic video. Attention to erotic cues was assessed using three methods: a written quiz, a visual quiz, and a self-reported distraction measure. Genital and psychological sexual responses were also measured. Self-reported distraction and written quiz scores most accurately represented the level of distraction present, while self-reported distraction also corresponded with a decrease in genital arousal. Findings support the usefulness of self-report measures in conjunction with a brief quiz on the erotic material as the most accurate and sensitive ways to simply measure experimentally-induced distraction. Insight into distraction assessment techniques will enable evaluation of naturally occurring distraction in patients suffering from sexual problems.     

Managing Relational Transgressions as Revealed on Facebook: The Influence of Dependence Power on Verbal Versus Nonverbal Responses

Dependence power is defined by the control a less dependent partner is perceived to have by the more dependent individual in a close relationship. Guided by assumptions about dependence power, we examined how individuals manage perceived relational transgressions by partners on Facebook, distinguishing between face-to-face responses versus those that are expressed nonverbally (through monitoring or maintenance behaviors) on the site. Participants included 290 females and 210 males in a dating relationship who completed measures of dependence power and Facebook use. Participants then viewed a screenshot reflecting a hypothetical Facebook partner transgression that varied by potential threat (high versus low). Finally, participants completed measures of perceived threat and a measure of responses to the transgression (monitoring and maintenance). Dependence power was associated with perceptions of the threat of a transgression, the likelihood of confronting a partner face-to-face about the perceived transgression, and engaging in Facebook monitoring behavior after a perceived transgression. Dependence power was not significantly associated with maintenance responses.     

An fMRI Study of Responses to Sexual Stimuli as a Function of Gender and Sensation Seeking: A Preliminary Analysis

Although sexual cues produce stronger neural activation in men than in women, mechanisms underlying this differential response are unclear. We examined the relationship of sensation seeking and the brain’s response to sexual stimuli across gender in 27 subjects (14 men, M = 25.2 years, SD = 3.6, 85.2% Caucasian) who underwent functional magnetic resonance imaging (fMRI) while viewing sexual and nonsexual images. Whole-brain corrected significant clusters of regional activation were extracted and associated with gender, sensation seeking, and sexual behaviors. Men responded more to sexual than nonsexual images in the anterior cingulate/medial prefrontal cortex (ACC/mPFC), anterior insula/lateral orbitofrontal cortex, bilateral amygdala, and occipital regions. Sensation seeking related positively to ACC/mPFC (r = 0.65, p = 0.01) and left amygdala (r = 0.66, p = 0.01) response in men alone, with both of these correlations being significantly larger in men than in women (ps < 0.03). The relationship between brain responses and self-reported high-risk and low-risk sexual behaviors showed interesting, albeit nonsignificant, gender-specific trends. These findings suggest the relationship between sexual responsivity, sensation seeking, and sexual behavior is gender specific. This study indicates a need to identify the gender-specific mechanisms that underlie sexual responsivity and behaviors. In addition, it demonstrates that the nature of stimuli used to induce positive mood in imaging and other studies should be carefully considered.     

Peripheral Stimulus Localization by Infants of Moving Stimuli on Complex Backgrounds

This study examined the effect of attention in young infants on the saccadic localization of dynamic peripheral stimuli presented on complex and interesting backgrounds. Infants at 14, 20, and 26 weeks of age were presented with scenes from a Sesame Street movie until fixation on a moving character occurred and then presented with a second segment in the scene in which the character movement occurred in a new location. Localization of the moving character in the new location was faster when the infant was engaged in attention than when inattentive, for scenes in which the character moved from one location to another, or scenes in which the character stopped moving and characters in new locations began moving. However, localization of the character was slower during attention when the first character disappeared and a different character appeared in a new location. We also found a decrease in the linear component of the main sequence in the saccade characteristics over the three testing ages, and attention affected the main sequence for infants at the two oldest ages. These results partially replicate prior findings showing that attention to a focal stimulus affects localization of peripheral stimuli, but suggest that the nature of the stimuli being localized modifies the role of attention in affecting eye movements to peripheral stimuli.     

The Role of Context in the Categorization of Hybrid Toy Stimuli by 18‐Month‐Olds

Using a sequential touching procedure, we examined whether 18‐month‐olds could use different categorization strategies adaptively as a function of context. Infants were presented with test toys of land animals (quadrupeds), cars, and hybrids made by recombining car parts with animal parts. Infants who experienced a context emphasizing a taxonomic divide were subsequently more likely to form categories that reflected a taxonomic divide, whereas infants who experienced a context emphasizing a partonomic divide were subsequently more likely to form categories based on functional parts. These results suggest that 18‐month‐olds can adapt their categorization strategies flexibly in accordance with ambient contextual cues. This adds to the growing body of evidence that early categorization is flexible and not rigidly tied to characteristic features in the environment.     

Mental Rotation of Dynamic,Three‐Dimensional Stimuli by 3‐Month‐Old Infants

Mental rotation involves transforming a mental image of an object so as to accurately predict how the object would look if it were rotated in space. This study examined mental rotation in male and female 3‐month‐olds, using the stimuli and paradigm developed by Moore and Johnson (2008) . Infants were habituated to a video of a three‐dimensional object rotating back and forth through a 240° angle around the vertical axis. After habituation, infants were tested both with videos of the same object rotating through the previously unseen 120° angle, and with the mirror image of that display. Unlike females, who fixated the test displays for approximately equal durations, males spent significantly more time fixating the familiar object than the mirror‐image object. Because familiarity preferences like this emerge when infants are relatively slow to process a habituation stimulus, the data support the interpretation that mental rotation of dynamic three‐dimensional stimuli is relatively difficult—but possible—for 3‐month‐old males. Interpretation of the sex differences observed in 3‐ and 5‐month‐olds’ performances is discussed.     

Therapeutic Responses to Communities Affected by Disasters: The Contribution of Family Therapy

This article is underpinned by the premise that for recovery, healing and post‐traumatic growth to occur after traumatic events such as technological and natural disasters, massacres and terrorist attacks, effective therapeutic services need to be offered at both the individual and community level. Frequently, responses to such traumatic instances have been conceptualised as discrete, polarised interventions offered by various groups of health and welfare professionals at various points post the traumatic event. Traditionally when therapeutic interventions are considered, many practitioners assume that the response would, and should, focus primarily and narrowly, on individuals or their families and the symptoms of post‐traumatic stress. Conversely, the perceived role of community wide interventions has been unnecessarily limited to disaster relief or organised emergency responses most usually offered at the time of the crisis. The consequence of these limited understandings is an apparent failure to explore fully the therapeutic or mediating role of social or community support in surviving trauma. Interventions encompassing the level of community might be therapeutic in two fundamental ways. First, if practitioners embraced ideas from systemic family therapy literature, ideas that acknowledge the importance of social networks, this would encourage a more holistic vision of resilience and recovery. Second, if practitioners recognised that whole communities and social networks might also be traumatised, they could provide support and interventions oriented toward healing at this broader level.     

Interviews by Telephone and in Person: Quality of Responses and Field Performance

A small carefully controlled field experiment tests the effectsof alternative interviewing strategies on the quality of responsesand on field performance. Measures include ability to answercomplex knowledge and attitudinal items, response validity,and willingness and consistency in providing personal information.Field performance is assessed by examining differential lengthof the interview, number of contacts required, suitable timesfor interviewing, respondent preferences for interview strategy,and interviewer effects.
