The conditioning of textual responses using “extrinsic” reinforcers

Six 4-year-old Ss were presented with a textual program consisting of 26 words arranged so the word stimuli were gradually combined into sentences and then short “stories.” Three Ss were given the No-Reinforcement condition first, and only social reinforcers were presented. They were switched to the Reinforcement condition as soon as they requested discontinuance of the activity. The other three Ss were given Reinforcement—No Reinforcement—Reinforcement treatments. The No-Reinforcement treatment in this case lasted until S requested discontinuance of the activity. The reinforcers were mixed edibles and trinkets, as well as tokens backed up by small plastic toys on a 1:24 ratio. The unit of response was the number of new texts acquired as a result of each of the 45-min experimental sessions. It was demonstrated that the program, procedure, and reinforcement conditions produced curves which are analogous to those produced in common operant-conditioning procedures. The results indicate that other operant principles may be studied in this significant area of human behavior, with important practical consequences.     

Reflections on a Community Psychology Setting and the Future of the Field

The 50th anniversary of the Swampscott Conference offers an opportunity to reflect on a community psychology setting, The Consultation Center at Yale, that was formed in response to the 1963 Community Mental Health Act and the 1965 Swampscott Conference. The Center has flourished as a community psychology setting for practice, research, and training for 39 of the 50 years since Swampscott. Its creation and existence over this period offers an opportunity for reflection on the types of settings needed to sustain the field into the future.     

Pushing Up on the Glass Ceiling of Female Muscularity: Women’s Bodybuilding as Edgework

Women bodybuilders exemplify gendered deviance and risk a social stigma on top of the physical risk of partaking in this demanding sport. In the current study, we utilize Stephen Lyng’s (1990, 2005) theoretical concept of “edgework” to understand what motivates women bodybuilders to engage in this high-risk behavior. Our qualitative analysis of 29 women bodybuilders' responses to open-ended survey questions reveals that the three components of edgework (activity, skill, and sensation) are evident in their training and dietary regimens. Overall, this study offers an important theoretical contribution to the study of women’s bodybuilding while also extending Lyng’s edgework model to this understudied phenomenon.     

Emotion recognition in children with Fetal Alcohol Spectrum Disorders

There is a limited amount of research that examines social-emotional functioning in children with Fetal Alcohol Spectrum Disorder (FASD), and the majority of it relies on parent and teacher reports of social impairments. Because these provide broad measures of social function, they fail to elucidate the underlying specific skills with which this group of children has difficulty. The current study examines emotion-recognition abilities in children with FASD, as it plays a central role in social interaction. Participants were 22 children with diagnosed FASD (ages 8–14), and age- and gender-matched typically developing controls. Tasks included measures of emotion recognition from three nonlinguistic modalities: facial expressions, emotional tone of voice, and body positioning and movement. Participant’s parents completed measures of adaptive and behavioral function that were related to children’s performance on aspects of emotion recognition. Overall, the results show that children with FASD have more difficulties with emotion recognition than typically developing age-matched peers, but these difficulties may not be clinically significant (e.g., smaller effect size) or may be specific to the age of the individual exhibiting the emotion (i.e., child vs. adult). These results are discussed in the context of previous studies.     

Prediction and control as determinants of behavioural uncertainty: effects on task performance and heart rate reactivity.

Control or control-belief is often viewed as being directly instrumental in facilitating coping mechanisms in aversive situations, and yet the empirical evidence for the beneficial effects of control is inconclusive. In this study we investigated the role of predictability in determining the effects of perceived control during an aversive reaction time task. Fifty-six subjects were allocated to one of four groups; predictable-control, predictable-no control, unpredictable-control, unpredictable-no control. In the predictable conditions, subjects could temporally predict the occurrence of an aversive noise. In the perceived control conditions, duration of the aversive tone was contingent on subject's performance. All subjects were matched in terms of the nature of the task and in the number and time of receipt of both the warning signal and noise. Heart rate reactivity and two performance parameters were measured, reaction time and performance increase. Both predictability and control-belief led to a reduction in heart rate reactivity, although they appeared to function independently and at different points in the sequence of events. That is, predictability or perceived control was sufficient to mitigate the effects of an aversive situation. Neither perception of control or predictability led to better task performance. These results are discussed in terms of behavioural uncertainty explanations.     

Personality Disorders in Older Adult Inpatients with Chronic Mental Illness

It has been hypothesized that some types of personality disorders tend to remit with age whereas others may become more prominent. The present study determined the prevalence and nature of 13 personality disorders with a self-report inventory (Coolidge Axis II Inventory) in an older group of chronically mentally ill inpatients (N = 30, mean age = 63 years) and a younger group of similar patients (N = 30, mean age = 39 years). All patients met DSM-IV criteria for either Schizophrenia, Schizoaffective Disorder, Bipolar Disorder, or recurrent severe Major Depression with psychotic features. The prevalence rate of personality disorders was high for both groups: 58% for the older sample and 66% for the younger group. The younger group was more likely to be diagnosed Antisocial, Borderline, Passive-Aggressive, Sadistic, and Schizotypal, but the groups were not different in the rates of Obsessive-Compulsive Disorder. This study supports the hypothesis that some personality disorders remit with age. However, no evidence was found to suggest that other personality disorders become more prominent in older adult psychiatric populations. Suggestions for future research are offered.

Probability of reciprocation in repeated prisoner's dilemma games

Both social cooperation and self‐control require reciprocation. In social cooperation situations a single person's cooperative act, if not reciprocated by others, would be unreinforced both immediately and in the long term. Similarly, a single act of self‐control (refusing a single cigarette, for example), if not followed up by other such acts, would also be unreinforced immediately and in the long term. The present experiments varied probability of reciprocation in a prisoner's dilemma‐like game that could resemble a social cooperation or a self‐control situation. Participants earned points by playing against a computer. The computer offered the participant a choice between 5 or 6 points (‘cooperation’ by the computer) or between 1 or 2 points (‘defection’ by the computer). The participant's choice of the lesser alternative (‘cooperation’) or the greater alternative (‘defection’) on the current trial led, respectively, to cooperation or defection by the computer on the next trial with a probability (probability of reciprocation, PR) which could vary. When PR was greater than 63%, consistent cooperation maximized the participant's earnings. When PR was less than 63%, defection maximized earnings. Three conditions were studied: PR signaled by spinners; PR unsignaled; PR unsignaled with participants believing that they were playing with another person, not the computer. With PR = 100% (‘tit‐for‐tat’) and PR = 50%, the modal participant maximized earnings under all three conditions. With PR = 75%, participants maximized earnings only when PR was signaled. These results indicate that differences between people's tendency to cooperate with other people (social cooperation) and their tendency to cooperate with their own future interests (self‐control) may lie in differences in subjective PR.
