A comparison of classical eyelid conditioning in adults and infants

In a classical conditioning procedure an eyeblink-eliciting tap to the glabella (the flat region of skin between the eyebrows) was presented 500 ms after the onset of a mild l-kHz tone. As tone-tap presentations proceeded, the probability of an eyeblink during the latter part of the tone increased in both infants (median age 8 months) and adults, but the infants were slower to condition than the adults and were more variable. Overall, the latency of the conditioned response to tone was significantly longer for infants than for adults, but the latency of the unconditioned response to tap was significantly shorter for infants than for adults.     

Maximizing the therapeutic effectiveness of small psychotherapy groups

Little attention has been paid in the literature to the ways in which psychotherapy groups of fewer than five members can be led effectively. The conditions leading to small groups are presented, including both dynamic and circumstantial conditions arising in the institution, the group, and the therapist. The dynamics of small groups are described based on social psychology research and clinical observations. The paper concludes by presenting therapist and member characteristics as well as therapeutic techniques which contribute to the maximal effectiveness of groups with fewer than five members.     

Relationship between sex-role attitudes and personality traits and the revised sex-role behavior scale

Two hundred college men and women completed self-report measures of sex-role traits (Personal Attributes Questionnaire), attitudes (Attitudes Toward Women Scale), and behavior (Sex-Role Behavior Scale). Intercorrelations among the three measures were examined to test two competing theoretical perspectives which dominate sex-role research today. The social learning point-of-view of Janet Spence and her colleagues asserts a general independence of sex-role personality traits, attitudes, and behaviors. The cognitive-developmental theory of Sandra Bem asserts that sex-role phenomena are fairly closely interrelated, at least for sex-typed individuals whose gender schemas cause them to adhere closely to traditional sex-role norms in their self-concepts and behavior. Findings of moderate relationships between masculine, feminine, and sex-specific personality traits, and the corresponding interest/behavior scales of the Sex-Role Behavior Scale, and between sex-role attitudes and behaviors lend partial support to both perspectives.

An emerging research agenda for investigative interviewing: hypotheses from the narrative action system

The present issue of JIP-OP brings together an intriguing range of papers that cover a wide range of aspects of testimony and aspects of investigative interviewing. They show how the considerations of how testimony is obtained is broadening out from the memory improvement strategies that once dominated this area with attempts to detect deception, to cover many aspects of how testimony is obtained. This draws attention to the need for more careful examination of the variations in testimony eliciting processes that will be responsive to differences in context and crime. A research agenda is therefore proposed that draws on developments in the understanding of psychological differences between crimes. This research would study the relationship between the psychological processes underpinning offence actions and the interview behaviour of suspects or witnesses. With regard to suspects, recent developments in the modelling of offence style have indicated a narrative basis (narrative action system model) for understanding the patterns of offence actions and the perpetrator's psychological background and characteristics that can be inferred from these. It is therefore suggested that the Hero's Quest, Professional's Adventure, Revenger's Tragedy, and Victim's Irony offending narratives and the Object, Vehicle, and Person victim roles assigned within these, may provide a fruitful link to different patterns of interview behaviour, with consequent implications for approaches to interviewing.

Elements of a plan-based theory of speech acts

This paper explores the truism hat people think about what hey say. It proposes that, to satisfy heir own goals, people often plan their speech acts to affect their listeners' beliefs, goals, and emotional states. Such language use can be modelled by viewing speech acts as operators in a planning system, thus allowing both physical and speech acts to be integrated into plans. Methodological issues of how speech acts should be defined in a plan-based theory are illustrated by defining operators for requesting and informing. Plans containing those operators are presented and comparisons are drawn with Searle's formulation. The operators are show to be inadequate since they cannot be composed to form questions (requests to inform) and multiparty requests (requests to request). By refining the operator definitions and by identifying some of the side effects of requesting, compositional adequacy is achieved. The solution leads to a metatheoretical principle for modelling speech acts as planning operators.
