Social representation of aggression as an explanation of gender differences: A preliminary study

Academic theories of aggression can be dichotomized as expressive (in which aggression results from a failure of self control) or instrumental (in which aggression represents the exercise of control over others). We propose that the two sexes hold a parallel distinction in their social representations of aggression; women subscribe to an expressive model, men to an instrumental model. A 20-item questionnaire was generated by systematic comparison of the two theories with respect to their differential predictions concerning perceived social value, proximate causes, relevant emotions and congnitions, form, aim, social facilitators, and reputational aspects of aggression. Factor analysis indicated a first factor of expressive-instrumental aggression on which all items had significant loadings. A significant correlation (.46) was found between gender and questionnaire score confirming the hypothesis. The notion of gender-specific social representations is discussed in terms of its ability to coherently interpret patterns of differences in aggression found in experimental and observational studies.     

How Lloyd Morgan's canon backfired

Lloyd Morgan's Canon is usually represented as a brave step towards mechanistic behaviourism. Morgan himself, however, was convinced that the behaviour of animals and humans could only be treated in intentionalist terms. In fact, not only the spirit but the details of his Canon have been consistently misunderstood. It was turned around by Neo-Cartesians within psychology and evolutionary biology to attack the very ground that Morgan shared with Darwin—the assumption that organisms are “no mere puppets in the hand of circumstances.” Morgan did not formulate his Canon in “revolt” against Romanes's anthropomorphic approach to comparative psychology. An examination of Morgan's early views reveals that his Canon represented a move towards, not against, Romanes's idea of an animal psychology. Before the Canon, Morgan had denied the very possibility of a comparative psychology.     

Assessing the Child's Cognitive Home Environment Through Parental Report; Reliability and Validity

In a series of investigations with poor minority families, we examined the reliability and validity of the StimQ, an office-based interview of children's cognitive home environment. Researchers and practitioners alike recognize the importance of assessing meaningful dimensions of children's early experiences, particularly in families where children may be at risk for later cognitive delay. To date, methodological approaches to the study of parenting have most often relied on home visits and/or labour-intensive observations and coding. Our findings suggest that valid and reliable data about the cognitive environments of poor children can be obtained through maternal report, thereby offering applied scientists a useful alternative to assessing children's early experiences. © 1996 John Wiley & Sons, Ltd.     

Decreasing Neuroleptic Doses in Older Adults with Schizophrenia

This prospective study of 27 older adults, residing in long-term care facilities, examined the effects of reducing neuroleptic medications to the point of controlling symptoms and reducing side effects. Schizophrenia is a challenging health care condition that leads to delusions, hallucinations, disorganized speech, and a host of other symptoms. Unfortunately, medications control many of the symptoms but cause unwanted side effects unless monitored closely and regulated to each person's needs. This study addresses six research questions related to the reduction of neuroleptic medications. Study findings related to neuroleptic medication dose reduction were encouraging. Additionally, the findings strongly suggest that health care providers working with older adults with the diagnosis of schizophrenia would benefit from planned educational programs about behavior, observations, and medications.     

Visual similarity effects in immediate verbal serial recall

The role of visual working memory in temporary serial retention of verbal information was examined in four experiments on immediate serial recall of words that varied in visual similarity and letters that varied in the visual consistency between upper and lower case. Experiments 1 and 2 involved words that were either visually similar (e.g. fly, cry, dry; hew, new, few ) or were visually distinct (e.g. guy, sigh, lie; who, blue, ewe ). Experiments 3 and 4 involved serial recall of both letter and case from sequences of letters chosen such that the upper- and lower-case versions were visually similar, for example Kk, Cc, Zz, Ww , or were visually dissimilar, for example Dd, Hh, Rr, Qq . Hence in the latter set, case informationwas encoded interms of both the shape and the size of the letters. With both words and letters, the visually similar items resulted in poorer recall both with and without concurrent articulatory suppression. This visual similarity effect was robust and was replicated across the four experiments. The effect was not restricted to any particular serial position and was particularly salient in the recall of letter case. These data suggest the presence of a visual code for retention of visually presented verbal sequences in addition to a phonological code, and they are consistent with the use of a visual temporary memory, or visual "cache", in verbal serial recall tasks.     

Perceived Barriers to Treatment Participation and Treatment Acceptability Among Antisocial Children and Their Families

This study examined the role of perceived barriers to participation in treatment and the acceptability of treatment among children and parents. Children (N = 144, ages 6–14) referred for outpatient treatment for oppositional, aggressive, and antisocial behavior and their families participated. The main findings were that: (a) perceived barriers to participation in treatment predicted treatment acceptability as rated by children and parents; (b) the effect was not accounted for by socioeconomic disadvantage, parent psychopathology and stress, and severity of child dysfunction; and (c) treatment acceptability was related to therapeutic change in the children over the course of therapy but the relation was small. Overall, the findings indicate that families vary considerably in the barriers they perceive in coming to treatment and that these barriers influence the extent to which they and their children evaluate the acceptability of the treatments they receive. The implications of treatment acceptability for evaluation and delivery of psychotherapy are discussed.     

Behavioral and pharmacological treatments for tourette syndrome: A review

This article reviews the published treatment outcome research on pharmacological and behavioral treatments for Gilles de la Tourette syndrome (TS). Controlled group outcome studies of pharmacological treatments show about a 50–60% reduction in tics with haloperidol and pimozide and about a 20% reduction with clonidine. A controlled group outcome study and several within-subject design studies of behavioral treatments show about a 90% reduction in tics with habit reversal training. A large number of case studies generally confirm these results and also show benefits from other behavioral treatments such as relaxation training, self-monitoring, and contingency management. Clinical limitations of TS drugs are that they produce side effects in 50–85% of the patients and require continuous use, and long-term compliance with the medications is limited. The primary limitation of behavioral treatments is that they require a large initial time commitment. The methodological strengths of the controlled drug studies are the use of double-blind and group designs. For the behavioral studies, the strengths are rigorous recording and controlled within-subject designs.
