Motion information in iconic memory

Motion perception was investigated in two experiments using Sperling's partial report procedure. In Experiment 1, subjects were presented with 8 moving squares; at array offset an arrow cued subjects to locate all squares moving in the direction of the arrow. The partial report was found to be superior to the whole report and this was taken as evidence for the existence, in iconic memory, of information about the direction of motion. The second experiment revealed only a minor decay in this superiority with the indicator delayed up to 1 sec. The importance of optical transformations in vision was stressed and it was argued that information processing models need pay greater attention to them.     

A comparison of the disturbingness of behaviors related to learning disability and emotional disturbance

Behaviors thought to be characteristic of emotional disturbance or learning disabilities were investigated through ratings of teachers with regard to the relative disturbingness of the behaviors. Obtained differences suggested that behaviors characteristic of emotional disturbance were rated as more disturbing than those of learning disabilities; differences within sets of characteristic behaviors were also indicated. Results are discussed with regard to implications for teacher expectancies and labeling research.     

The Making of an Interdisciplinary Partnership: The Case of the Chicago Food System Collaborative

Interdisciplinary partnerships foster innovation to address pressing social problems. This paper describes an interdisciplinary partnership called the Chicago Food System Collaborative (CFSC) composed of a team of partners from four academic institutions and three community-based organizations representing a total of eight disciplines that included: community development and community organizing, community psychology, geography, nursing, nutrition, public health, sociology, and urban planning and policy. Partners came together to address the issue of access to healthy foods and nutrition in a working class African American neighborhood. We analyze and discuss the core principles that guided the partnership and its impact across three dimensions: understanding through interdisciplinary action research, building capacity, and facilitating innovations in practices and policies. Despite the challenges of interdisciplinary partnerships, the potential benefits and impact of such efforts reflect their value as a comprehensive approach to addressing complex social problems.     

Psychoanalytic Psychotherapy for Severely Disturbed Borderline Patients: Observations on the Supervision Group of Psychotherapists

The authors describe the role of a supervision group of psychotherapists within a wider therapeutic field for severely disturbed borderline patients. The group concentrates on the transference and countertransference, seen according to Racker’s distinction between concordant and complementary identifications. The implications of the prevalence of the complementary identifications over the concordant identifications of the therapists to their patients and the resulting regression to primitive defense mechanisms can be counterbalanced by the group’s integrative functioning as receiver (1) of a variety of information about the patient, (2) of the therapist’s attempt to understand and synthesize, and (3) of the therapist’s countertransference reactions to his patient. The major discrepancies between the various conceptions of the borderline patients’ psychic world and the appropriate therapeutic technique to be applied are also discussed, as well as the way the group filters the information and integrates the therapeutic thought. It might be said, therefore, that, in the “inpatient” phase of the individual psychotherapy, the group of psychotherapists functions, for the patient and the treatment, in a synthesizing context, as it provides the therapist with a space of integration for his split-off part of self and object representations, which the therapist makes use of for his patient.*Members of the Athens University Project for Borderline Patients’ research team consisting of psychoanalysts and psychotherapists, Eginition Hospital, 74 Vas Sophias Avenue, Athens 11528, Greece.Maria Chatziandreou, M.D., is a member of the Hellenic Psychoanalytical Society.Haris Tsani, M.D., is a candidate of the Hellenic Psychoanalytical Society.Nikos Lamnidis, M.D., is a candidate of the Hellenic Psychoanalytical Society.Claire Synodinou, Ph.D., is a member of the Paris Psychoanalytical Society and an associate professor at Panteion University, Athens.Grigoris Vaslamatzis, M.D., is a training analyst of the Hellenic Society of Psychoanalytic Psychotherapy and an associate professor of psychiatry at Athens University.Address correspondence to: Maria Chatziandreou, M.D., 1-3, Skippi Street, 11525 Athens, Greece.     

Comment on short-term variation in subjective sleepiness

Subjective sleepiness at different times is often measured in studies on sleep loss, night work, or drug effects. However, the context at the time of rating may influence results. The present study examined sleepiness throughout the day at hourly intervals and during controlled activities [reading, writing, walking, social interaction (discussion), etc.] by 10-min. intervals for 3 hr. This was done on a normal working day preceded by a scheduled early rising (to invite sleepiness) for six subjects. Analysis showed a significant U-shaped pattern across the day with peaks in the early morning and late evening. A walk and social interaction were associated with low sleepiness, compared to sedentary and quiet office work. None of this was visible in the hourly ratings. There was also a pronounced afternoon increase in sleepiness, that was not observable with hourly ratings. It was concluded that there are large variations in sleepiness related to time of day and also to context and that sparse sampling of subjective sleepiness may miss much of this variation.     

Group identification and outgroup attitudes in four South African ethnic groups: a multidimensional approach

Although Sumner's ethnocentrism hypothesis, which expects stronger group identification to be associated with more negative outgroup attitudes, has been widely accepted, empirical findings have been inconsistent. This research investigates the relationship of four dimensions of ethnocultural group identification previously proposed by Phinney, that is, salience, evaluation, attachment, and involvement, with attitudes to ethnic outgroups in four South African ethnocultural groups (Africans, Afrikaans Whites, English Whites, Indians). The findings supported the factorial independence of the four identification dimensions and indicated that only one, ethnocultural evaluation (ingroup attitudes), was systematically related to outgroup attitudes, but the association could be positive, negative, or zero. Both functionalist and similarity-dissimilarity approaches to intergroup relations seemed to provide plausible explanations for the pattern of relationships obtained between ingroup and outgroup attitudes.     

Comparison and contrast in perceptual categorization

People categorized pairs of perceptual stimuli that varied in both category membership and pairwise similarity. Experiments 1 and 2 showed categorization of 1 color of a pair to be reliably contrasted from that of the other. This similarity-based contrast effect occurred only when the context stimulus was relevant for the categorization of the target (Experiment 3). The effect was not simply owing to perceptual color contrast (Experiment 4), and it extended to pictures from common semantic categories (Experiment 5). Results were consistent with a sign-and-magnitude version of N. Stewart and G. D. A. Brown's (2005) similarity-dissimilarity generalized context model, in which categorization is affected by both similarity to and difference from target categories. The data are also modeled with criterion setting theory (M. Treisman & T. C. Williams, 1984), in which the decision criterion is systematically shifted toward the mean of the current stimuli.     

Letting a little nonverbal air into the room: Insights from acceptance and commitment therapy Part 1: Philosophical and theoretical underpinnings

In recent years, a new “wave” of mindfulness based Cognitive Behavior Therapies (CBT) has become popular. Such approaches include Acceptance and Commitment Therapy (ACT; Acceptance and commitment therapy: An experiential approach to behaviour change. New York: Guilford Press, 1999), Mindfulness-based Cognitive Therapy for Depression (Mindfulness-based cognitive therapy for depression: A new approach to preventing relapse. New York: Guilford Press, 2002), and Mindfulness-based Stress Management (Full catastrophe living: using the wisdom of your body and mind to face stress, pain, and illness. New York: Dell Publishing, 1990). In contrast to traditional CBT, these approaches often minimize attempts to change the form and frequency of dysfunctional thoughts. Is there any way to integrate traditional CBT with mindfulness based CBT? To answer this question, we discuss the philosophical and theoretical underpinnings of one form of traditional CBT (Rational-Emotive and Cognitive Behavioral Therapy) and one form of mindfulness based CBT (ACT). We argue that some aspects of each therapy can be integrated. However, in order to prevent techniques from being used haphazardly or inconsistently, we suggest that the different forms of CBT need to be driven by a common philosophical orientation (e.g., functional contextualism) and theoretical orientation (e.g., Relational Frame Theory).     

Apolipoprotein epsilon4 is associated with more rapid decline in odor identification than in odor threshold or Dementia Rating Scale scores

Individuals with the apolipoprotein E epsilon4 genetic risk factor for Alzheimer's disease (AD) show deficits in olfactory function. The purpose of the present study was to examine longitudinally odor identification (odor ID), odor threshold, picture identification, and global cognitive status in allele positive (epsilon4+) and negative (epsilon4-) persons. Participants were initially given the San Diego Odor Identification test, an odor threshold test, and the Dementia Rating Scale (DRS). Participants were re-tested approximately four years later. The results indicate: (1) odor ID declined more rapidly in epsilon4+ than in epsilon4- normal elderly adults; (2) neither group exhibited a significant decline in odor threshold, picture identification or DRS scores. These results suggest that declines in odor identification occur before declines in other measures of dementia in persons at risk for AD because of their APOE allele genetic status.     

Computational and behavioral markers of model-based decision making in childhood

Human decision-making is underpinned by distinct systems that differ in flexibility and associated cognitive cost. A widely accepted dichotomy distinguishes between a cheap but rigid model-free system and a flexible but costly model-based system. Typically, humans use a hybrid of both types of decision-making depending on environmental demands. However, children's use of a model-based system during decision-making has not yet been shown. While prior developmental work has identified simple building blocks of model-based reasoning in young children (1–4 years old), there has been little evidence of this complex cognitive system influencing behavior before adolescence. Here, by using a modified task to make engagement in cognitively costly strategies more rewarding, we show that children aged 5–11-years (N = 85), including the youngest children, displayed multiple indicators of model-based decision making, and that the degree of its use increased throughout childhood. Unlike adults (N = 24), however, children did not display adaptive arbitration between model-free and model-based decision-making. Our results demonstrate that throughout childhood, children can engage in highly sophisticated and costly decision-making strategies. However, the flexible arbitration between decision-making strategies might be a critically late-developing component in human development.
