Motion coherence and conjunction search: Implications for guided search theory

Feature integration theory has recently been revised with two proposals that visual conjunction search can be parallel under some circumstances—either because items with nontarget features are inhibited, or because items with target features are excited. We examined whether excitatory or inhibitory guidance controlled conjunction search for an X oscillating in one direction among Os oscillating in that direction and Xs oscillating in another. Search was affected by whether items oscillated in phase with each other, and it was exceptionally difficult when items with target motion moved out of phase with each otherand items with nontarget motion moved out of phase. The results suggest that conjunction search can be guided both by excitation of target features and by inhibition of nontarget features.     

Client and counsellor narrative accounts of congruence during the most helpful and hindering events of an initial counselling session

The role of congruence in establishing and maintaining a therapeutic alliance has been emphasized by theorists within the humanistic/person‐centred tradition. However, there appears to be a lack of research that explores the processes occurring during moments of congruence or incongruence. The main objective of the present study was to gather qualitative data about congruence based on both participants’ narrative accounts of their subjective reactions during the most helpful and the most hindering event of an initial counselling session. Client and counsellor recollections of their experiences during these two events were stimulated through the replay of a video‐tape after the session. The event identification came from the client through a Brief Structured Recall interview. During the hindering event, both participants were incongruent. There was a mismatch between what they were feeling and what they were expressing verbally and/or non‐verbally. At the same time the client was feeling criticised and offended by counsellor's confrontation. By contrast, during the helpful event both participants were congruent. The counsellor was experiencing empathic understanding toward his client and the client was feeling accepted and understood. The implication of these findings are discussed in terms of how congruence might affect the construction of significant events during the therapeutic hour.     

Friendship patterns of overseas students: A functional model1

The respondents were 30 foreign students at the University of Hawaii (6 each from Japan, Korea, the Philippines, Taiwan, and Thailand), and 6 host national (American) students, balanced for sex. The subjects identified their 5 best friends, and the 5 people with whom they spend most of their time. The subjects were then presented with a list of 15 activities, and identified a preferred companion for each of the situations. The data were used to test a functional model of the academic sojourn, which predicts that foreign students will belong to three social networks, in descending order of salience: a) a conational network whose function is to affirm and express the culture of origin; b) a network with host nationals, whose function is the instrumental facilitation of academic and professional aspirations; and c) a multinational network whose main function is recreational. The results confirmed the existence, predicted differential function, and salience hierarchy of these three social networks, and reconciled previous conflicting reports regarding the social relations of foreign students.     

Alliance-Outcome Associations in a Community-Based Social Skills Intervention for Youth With Autism Spectrum Disorder

Although the alliance is a consistent predictor of treatment outcomes in psychosocial interventions, few studies have examined this association among youth with autism spectrum disorder (ASD). In particular, youth-therapist alliance has never been examined in social skills interventions (SSIs), a common modality for this population. In this study, thirty-four youth with ASD (M_age = 12.41; 79% male) participated in a community-delivered, group-based SSI in a summer camp format led by eight Head Therapists (M_age = 32.12; 50% male). Early alliance and change in alliance over the course of the treatment were assessed via self- and observer-reported measures. Both self- and observer-rated alliance were associated with positive treatment outcomes as reported by parents (decreased problem behaviors) and other peers in the group (reciprocated friendship and social preference). These results provide the first evidence of the role of the alliance in an SSI for youth with ASD and add to the growing body of literature that demonstrates the importance of assessing and addressing the alliance in treatment for this population.     

The optic trajectory is not a lot of use if you want to catch the ball

According to linear optic trajectory (LOT) theory, fielders use the direction of curvature of theoptic trajectory to control the way they run to intercept the ball. Data presented by D. M. Shaffer and M. K. McBeath (2002) as support for LOT theory show that the optic trajectory of balls that will fall behind the fielder provide the cue that LOT theory predicts would send the fielder running forward, not backward. In this article, the authors show that watching these balls would provide the fielder with the cue that the optic acceleration cancellation (OAC) theory of interception predicts would send the fielder running backward. It appears that the fielders studied by Shaffer and McBeath were following the cue predicted by OAC theory, not that predicted by LOT theory.     

Predictable Mispredictions in the Context of Physical Activity and Sport: A Review

Theoretical models and research that aim to identify antecedents of participation in physical activities or sport can measure antecedents of physical activity behaviour through instruments that involve subjective predictions. In this article, we argue that such instruments may not reflect physical activity experiences or behaviour accurately because people are not very good predictors of future states. Additionally, we propose that mispredictions may be predictable because they are “caused” by tendencies to neglect processes related to hedonic adaptation and competing alternatives. We also suggest that it may be possible to improve measurement of antecedents through methods that focus respondents' attention on factors that cause mispredictions or through experiential sampling methods.     

Topic-focused analysis in a case of integrative psychotherapy with a father fearing his own anger

Even though evidence-based knowledge is considered the foundation of clinical practice, many clinicians question the clinical relevance of published research. Clinicians increasingly define themselves as having an integrative stance, in contrast to the tendency for most research to be based on clearly defined psychotherapies. Qualitative single case studies make it possible to generate knowledge about what actually occurs in integrative therapy. Topic change process analysis (TCPA) is used in the analysis of brief integrative therapy conducted by a very experienced psychotherapist drawing on a complex variety of therapeutic approaches. The client was a man in his late thirties, worrying about his strong anger, particularly related to one of his children. Analysis of topic areas, topic shifts, response patterns within topics and changes in perspective made it possible to identify key processes and key patterns of the therapy which resulted in a very positive outcome for the client. Implications of these findings for practice, and future research, are discussed.     

The generalized optic acceleration cancellation theory of catching

The generalized optic acceleration cancellation (GOAC) theory of catching proposes that the path of a fielder running to catch a ball is determined by the attempt to satisfy 2 independent constraints. The 1st is to keep the angle of elevation of gaze to the ball increasing at a decreasing rate. The 2nd is to control the rate of horizontal rotation necessary to maintain fixation on the ball. Depending on the lateral velocity of the ball relative to the fielder, this rate may be zero or constant at a negative or positive value. The authors show that a simulated fielder implementing the GOAC strategy follows a path indistinguishable from that of real fielders running to catch balls thrown on the same trajectories.     

Autobiographical memory deficits in schizophrenia

This study investigated autobiographical memory processes in a group of individuals diagnosed with schizophrenia and matched controls. The schizophrenia group displayed an overgeneral style of autobiographical memory retrieval on two widely used measures, and displayed problems retrieving both autobiographical facts and events. They showed a specific impairment in the recall of autobiographical events and facts in early adulthood, around the time of onset of their illness. Retrieval deficits were independent of mood state and premorbid intellectual functioning. The magnitude of the deficits in autobiographical memory retrieval specificity were considerably greater than any general impairments in episodic and working memory.
