Effects of alcohol intoxication and aggressivity on aggressive verbalizations during anger arousal

We examined the moderating effect of dispositional aggressivity on the relationship between alcohol intoxication and aggressive verbalizations. Using a laboratory anger-induction task that simulated an interpersonal conflict as a method to assess aggressive verbalizations (the articulated thoughts in simulated situations paradigm), 70 participants (33 women, 37 men) consumed either an alcoholic or a placebo beverage, and then imagined a series of audiorecorded interpersonal scenarios. Two blind-to-condition raters assessed the frequency of participants' aggressive verbalizations (insults, aggressive threats, belligerent provocations) articulated during anger arousal. Aggressivity was assessed using a standard measure of dispositional aggression. Results supported the aggressivity moderation hypothesis: intoxicated participants high in aggressivity responded with significantly more aggressive verbalizations relative to low-aggressivity participants regardless of beverage condition, and three times more aggressive verbalizations relative to the high-aggressivity/placebo group. There were no gender effects. These data support the hypothesis that alcohol potentiates aggression primarily among individuals at dispositional risk for engaging in such a behavior. Aggr.

Experience matters: the impact of doing versus watching on infants' subsequent perception of tool-use events

Prior work suggests that active experience affects infants' understanding of simple actions. The present studies compared the impact of active and observational experience on infants' ability to identify the goal of a novel tool-use event. Infants either received active training and practice in using a cane to retrieve an out-of-reach toy or had matched observational experience before taking part in a habituation paradigm that we used to assess infants' ability to identify the goal of another person's tool-use acts. Active training alone facilitated 10-month-old infants' ability to identify the goal of the tool-use event. Active experience using tools may enable infants to build motor representations of tool-use events that subsequently guide action perception and support action understanding.     

The effect of light color on muscular strength and power

The purpose of this study was to assess the effect of the color of light in a room on muscular strength and power. A convenience sample of 18 men (M age = 20.4 yr., SD = 1.2) performed a modified Wingate Anaerobic Cycle Test for muscular power and a hand grip strength test in each of the following conditions: red, blue, and white (neutral) ambient light. A repeated-measures multivariate analysis of variance indicated that average muscular power was significantly higher when performing the test in the room with red light compared to rooms lit with blue light or white light. The results also indicated that grip strength was significantly higher in the room lit with white light as compared to the room lit with blue light.     

When marital interaction and intervention researchers arrive at different points of view: the active listening controversy

In 1998, John Gottman and his associates published an article which asserted that training 'active listening' between couples was an ineffective therapeutic intervention. Not surprisingly, this claim generated considerable controversy, particularly in relation to treatment and educational models that were heavily dependent on active listening as a major part of their intervention programmes. The authors of one such approach, the Prevention and Relationship Enhancement Program (PREP), were particularly vocal in their disagreement with Gottman's conclusions. This paper provides an account of the controversy, a summary of the current status of the debate and a discussion of the remaining unanswered questions.     

The Relationship Between Therapist Characteristics and Decreased Medical Utilization: An Exploratory Study

This was an exploratory study examining the relationship between the therapist characteristics of age, experience, gender, and profession and the medical utilization of clients. Marriage and family therapists, clinical social workers, and psychologists participated in the study along with 197 clients as identified by archival research methods. The results of logistic regression analysis suggested that psychotherapy in general, rather than professional training or therapist characteristics is responsible for reductions in healthcare utilization.     

Ten‐month‐old infants use prior information to identify an actor's goal

For adults, prior information about an individual's likely goals, preferences or dispositions plays a powerful role in interpreting ambiguous behavior and predicting and interpreting behavior in novel contexts. Across two studies, we investigated whether 10‐month‐old infants’ ability to identify the goal of an ambiguous action sequence was facilitated by seeing prior instances in which the actor directly pursued and obtained her goal, and whether infants could use this prior information to understand the actor's behavior in a new context. Experiment 1 demonstrated that the goal preview impacted infants’ subsequent action understanding, but only if the preview was delivered in the same room as the subsequent action sequence. Experiment 2 demonstrated that infants’ failure to transfer prior goal information across situations arose from a change in the room per se and not other features of the task. Our results suggest that infants may use their understanding of simple actions as a leverage point for understanding novel or ambiguous actions, but that their ability to do so is limited to certain types of contextual changes.     

IS PERCEPTION A PROPOSITIONAL ATTITUDE?

It is widely agreed that perceptual experience is a form of intentionality, i.e., that it has representational content. Many philosophers take this to mean that like belief, experience has propositional content, that it can be true or false. I accept that perceptual experience has intentionality; but I dispute the claim that it has propositional content. This claim does not follow from the fact that experience is intentional, nor does it follow from the fact that experiences are accurate or inaccurate. I end by considering the relationship between this question and the question of whether experience has non-conceptual content.     

Assesement of young children

Discusses important issues and problems related to the assessment of young children. A review of the literature identifies major trends in the field of assessment in early childhood education. Authors conclude that with increased emphasis on assessment of young children, there is an increased need to develop teachers' skills in both selection and interpretation of appropriate formal and informal assessment techniques.     

Introduction to Behavioural Family Therapy for families with young children

This paper presents some suggestions for the implementation of Behavioural Family Therapy for families with young children. It attempts to bridge the gap between clinical research and practice by emphasizing the process of therapy delivery rather than the specific content of the behavioural approach. Suggestions for teaching behaviour management skills, contracting and the effective use of rewards and punishments are given. The common mistakes made by those working with Behavioural Family Therapy are addressed, and suggestions for working with single-parent families are given.
