Persistent behavior maintained by unavoidable shocks

Squirrel monkeys were trained on a multiple schedule in which 10-min periods on a continuous shock avoidance schedule, indicated by a yellow light, alternated with 10-min periods on a 1.5-min variable interval schedule of food reinforcement (VI 1.5). A white light indicated that VI 1.5 was in effect, except for the middle 2 min of the period on VI 1.5, in which a blue light appeared and terminated with the delivery of a 0.5-sec unavoidable shock. Stable response rates developed in the avoidance and VI 1.5 components. However, the highest response rates occurred in the blue, preshock stimulus. A series of experiments showed that responding in the blue stimulus persisted even when responding had been extinguished on both the VI schedule of food reinforcement and the shock avoidance schedule. Responding in the blue stimulus ceased when the blue stimulus terminated without shock or when it terminated with a response-contingent shock. Each time responding ceased, it was restored by terminating the blue stimulus with an unavoidable shock. When the blue stimulus was on throughout each session and unavoidable shocks were delivered at regular 10-min intervals, responding was well maintained. These results show that in monkeys that have been trained on a continuous avoidance schedule, unavoidable shocks can maintain responding even under conditions where responses have no programmed consequences.     

Profiles of Resilience and Psychosocial Outcomes among Young Black Gay and Bisexual Men

Young Black gay/bisexual men (YBGBM) are affected by contextual stressors—namely syndemic conditions and minority stress—that threaten their health and well‐being. Resilience is a process through which YBGBM achieve positive psychosocial outcomes in the face of adverse conditions. Self‐efficacy, hardiness and adaptive coping, and social support may be important resilience factors for YBGBM. This study explores different profiles of these resilience factors in 228 YBGBM in New York City and compares profiles on psychological distress, mental health, and other psychosocial factors. Four profiles of resilience were identified: (a) Low self‐efficacy and hardiness/adaptive coping (23.5%); (b) Low peer and parental support (21.2%); (c) High peer support, low father support (34.5%); and (d) High father and mother support, self‐efficacy, and hardiness/adaptive coping (20.8%). YBGBM in profile 1 scored markedly higher on distress (d = .74) and lower on mental health functioning (d = .93) compared to men in the other profiles. Results suggest that self‐efficacy and hardiness/adaptive coping may play a more important role in protecting YBGBM from risks compared to social support and should be targeted in interventions. The findings show that resilience is a multidimensional construct and support the notion that there are different patterns of resilience among YBGBM.     

Revisiting the role of recollection in item versus forced-choice recognition memory

Many memory theorists have assumed that forced-choice recognition tests can rely more on familiarity, whereas item (yes-no) tests must rely more on recollection. In actuality, several studies have found no differences in the contributions of recollection and familiarity underlying the two different test formats. Using word frequency to manipulate stimulus characteristics, the present study demonstrated that the contributions of recollection to item versus forced-choice tests is variable. Low word frequency resulted in significantly more recollection in an item test than did a forced-choice procedure, but high word frequency produced the opposite result. These results clearly constrain any uniform claim about the degree to which recollection supports responding in item versus forced-choice tests.     

Spirituality and religion in psychiatry: the impact of policy

ABSTRACT

Research and debate on the importance of spirituality and religion in psychiatry has led to a number of national and international policy initiatives, intended to clarify the boundaries of good practice and improve the way in which such matters are managed for the benefit of patients. Significant amongst these is the 2015 position statement of the World Psychiatric Association, the only such policy statement to date which has been internationally agreed. Preliminary evidence available suggests that this is having good effect in generating professional debate and further national policy initiatives in different countries. There is a need for further research on such policy initiatives to confirm whether or not they have the intended impact upon clinical practice and whether or not this in turn is beneficial for patients.     

A simple intervention for stereotypical engagement with an augmentative alternative communicative device

Although electronic devices may enhance the effectiveness of some behavioral interventions for children with autism spectrum disorders, such devices may also give rise to problem behavior such as repetitious button pressing (i.e., object stereotypy). Results of this study showed that a child with autism spectrum disorder only displayed high levels of object stereotypy on an iPad? when presses generated auditory output. Subsequently, results showed that when the participant used the iPad? without auditory output, his stereotypical behavior decreased and his manding for various items simultaneously increased.
