Movement and working memory: Patterns and positions in space

Five experiments are reported in which subjects were asked to remember short, visually presented sequences of whole body movement patterns, words, and spatial positions. The items were recalled in order in a memory span paradigm. During presentation of the items to be remembered subjects simply watched, or they carried out a concurrent activity involving articulatory suppression, movement to external spatial targets, or body-related movement. When the movement patterns to be remembered were familiar to subjects, movement span was not disrupted by articulatory suppression or movement to spatial targets but was disrupted by body-related movement. This movement suppression task, however, did not interfere with performance on a spatial span task or on verbal span. It is concluded that the memory for patterns of limb movement differs from memory for movement to spatial targets and that accounts of visuo-spatial processes in working memory involve the latter type of movement.     

Obedience as a function of experimenter competence

The purpose of this study was to investigate obedience to an E’s commands as a function of E competency. Based upon Orne’s (1962, 1969) discussion of the demand characteristics inherent in the typical aggression study, it was hypothesized that E incompetence would decrease S obedience. Competence was manipulated by: (1) presenting some Ss with a nervous and inexperienced E, and (2)“accidentally” killing the victim (a rat) midway through the experiment. Thirty-two undergraduate female Ss participated in the experiment—supposedly a study on the physiological effects of stress. Obedi6nce was operationalized as the difference, in simple reaction time, between trials on which Ss were told that their response might result in shock to the rat and trials on which they were told that their response might save the rat from shock. Significant differences in obedience were obtained between competent and incompetent E conditions, and a significant “kill” effect was found in the competent E conditidn. The results of this study suggested that the extreme acts of obedience observed in the laboratory (e.g., Milgram, 1963) occur only when E is perceived as competent. This finding imposes limits on the generalizability of laboratory studies of obedience.     

Brain-stimulation intensity, rate of self-stimulation, and reinforcement strength: an analysis through chaining

Reinforcement strengths of different intensities of brain stimulation were assessed by means of a two-member behavioral chain. A variable interval schedule of 30 sec was the first-member, and five lever presses, each rewarded with stimulation, was the second. It was found that response rate on the VI schedule continued to increase beyond the intensity value which produced peak rate on the second-member, self-stimulation lever. It was concluded (1) that brain-stimulation reinforcement strength cannot be assessed adequately by means of self-stimulation rate, and (2) the chaining technique employed in the present experiment appears promising as an analytical tool in brain-stimulation research. Finally, some aspects of the data suggested a fatigue or stimulation-adaptation phenomenon.     

Autobiographical reflections on what it means to experience disruption

Accepting disruption as an inevitable occurrence in life, five nurse-teacher-researchers explore their experience with being disruptive/being disrupted. Reflection on the all-encompassing embodied experience of disruption takes us through a process of exploration and meaning-making. We pause to show what it is like to be in-between the known and unknown in creating a life in academia through stories. Plotlines such as being in-between family and work; transplanted outsider seeking a sense of belonging; going into the chaos while feeling invisible; and self-induced disruption in response to loss illuminate our reflection. The metaphor of the breathturn allows us to reconstruct our experience and to discern possibilities beyond the usual negative connotations.     

Will the Mother-Group Have a Face? The Future of the Facilitating Environment

The author predicts that maintaining the responsible practice of group psychotherapy in the coming years will require attention to three areas of professional life. The training of group therapists must include group-as-a-whole, in addition to intrapsychic and interpersonal, theoretical constructs. A supportive network of professional colleagues must be available to provide consultation and continuing education. Finally, a culture that values the necessary components of group psychotherapy practice must be encouraged and supported.     

Critical Issues in Using Homework Assignments Within Cognitive-Behavioral Therapy for Schizophrenia

Presents an overview of the research findings to date and practical guidelines for the use of homework in cognitive-behavioral therapy for schizophrenia. In particular, the article outlines strategies to combat the common difficulties experienced when using homework with clients with schizophrenia and the types of homework assignments that may be most helpful. The empirical evidence suggests that cognitive-behavioral therapy incorporating homework assignments help clients to improve at least 60% more than those in treatment without homework. Despite that most therapy formulations incorporate homework as an integral component of treatment for schizophrenia, prior research has identified that practitioners consider homework to be less helpful for clients with delusions and hallucinations. Interventions to enhance homework compliance in the treatment of clients with schizophrenia are outlined.     

The influence of suggestions on children's reports of a unique experience versus an instance of a repeated experience

In Experiment 1 we compared the influence of misleading suggestions on 4‐, 6‐, and 8‐year‐olds' reports of details of an instance of a repeated experience versus a unique experience. For children who experienced the event repeatedly, some components remained constant across instances (fixed) whereas others varied (variable). Relative to children who had experienced the event only once, those who had experienced it repeatedly were less affected by suggestions regarding fixed details and more affected by suggestions regarding variable details. In Experiment 2 a misinformation effect was observed in responses to questions about variable details but not in responses to questions about fixed details.

Minimizing Mistreatment by Female Adults: The Influence of Gender-Based Social Categories and Personality Differences on Attitudes about Child Sexual Abuse

We investigated the effects of gender-based social categories (i.e., men, women, boys, and girls) on attitudes about child sexual abuse and individual differences in the use of such categories. In four experiments, we systematically varied perpetrators’ sex and victims’ sex. In three investigations, we assessed personality variables potentially related to participants’ use of these social categories. Across these four experiments, we varied perpetrator-victim relationships (teacher-student, neighbors) and victims’ ages. In experiment one, individuals had the least negative attitude about child sexual abuse involving adult female neighbors and eighth grade male neighbors. In experiment two, we replicated this effect with fifth grade victims and demonstrated that attitudes were moderated by individual differences in intolerance of ambiguity. In experiment three, we again replicated the aforementioned effect while (a) extending this finding to teacher-student relationships with eighth grade adolescent victims and (b) demonstrating the need for cognition was a moderator. In experiment four, we again replicated (a) our perpetrator sex/victim sex interactive effect and (b) need for cognition moderation while also demonstrating that these effects were applicable to fifth grade victims. Methodological limitations as well as clinical and policy implications (e.g., attenuating the underreporting incidents of child sexual abuse) are discussed.     

Increasing meal consumption in individuals with competing protective equipment

Individuals diagnosed with autism spectrum disorder may engage in self‐injurious behavior that can cause tissue damage. Protective equipment is sometimes used to decrease the severity of tissue damage when self‐injury occurs. However, wearing protective equipment may be incompatible with some forms of adaptive behavior, such as meal consumption. The purpose of the present analysis was to identify a treatment for increasing meal consumption in two adolescent males diagnosed with an autism spectrum disorder who wore protective equipment that interfered with self‐feeding. Three interventions were evaluated: modifying the protective equipment, manipulating the reinforcing efficacy of the meal, and arranging additional positive reinforcement for meal consumption in the absence of protective equipment. Modifying protective equipment and manipulating the reinforcing efficacy of the meal were effective for both participants. Additional positive reinforcement was evaluated and effective for one participant.
