Serial-Position Effects in Motor Short-Term Memory

This study examined the effect of the length of a series of movements on the recall of those movements. Subjects (n =45) were randomly assigned to one of three experimental groups with each group recalling either three, six, or nine movements on a linear-slide apparatus. The subjects, while blindfolded, were presented with each movement by actively moving to a stop. Recall occurred 5 sec after the last movement to a stop on a trial. All subjects were given nine trials, each containing a different series of to-be-recalled movements. Results indicated that absolute error of recall of the three movements increased in a linear fashion. However, for six and nine movements, a bowing effect of the recall curve was noted following the fifth position. A primacy effect was more ‘ evident than was a recency effect. Accuracy of recall was a function of list length up to six movements, after which accuracy was not further impaired.     

Effects of Local Muscular Fatigue Due to Isotonic and Isometric Exercise Upon Fractionated Reaction Time Components

Fractionated RT for a right knee-extension task was assessed on eight male and eight female Ss over eight treatment days. Following four consecutive days of 75 RT trials /day to insure stabilized strength and RT components, Ss were administered two days of bench stepping and two days of isometric exercise designed to induce muscular fatigue of the knee extensors. Significant strength decrements of up to 24% were induced by both the isotonic (bench stepping) and isometric exercise treatment conditions but no changes were observed in fractionated RT components. The results would seem to indicate that performance differences in fine-versus gross-motor skill tasks due to fatigue need to be more carefully examined.     

Geographical Concomitants of Negro Criminal Intelligence

This study attempts to demonstrate the relationship between teachers’ personal early experiences of attachment with their parents and their emotional, cognitive, and behavioral reactions to a hypothetical student's request to speak with them, expressed in short or detailed form. A similar procedure has been used by Perrine and Steele King for students, and now has been used for teachers. For this purpose, self-report questionnaires were administered to a sample of 395 female teachers. The results showed a significant relationship between parental bonding experiences and behavioral and emotional, but not cognitive, reactions to an hypothetical student's request. The optimal parenting group reported more positive emotional and behavioral reactions, while the affectionate control group reported more negative emotional reactions to the hypothetical student's request than the other groups. These results offer useful implications to be utilized in teachers’ training programs.     

Signal detection models for the same–different task

Signal detection models for the same–different task are presented. In contrast to the standard approach that only considers the proportion correct, the models apply to the full four by two same–different table. The approach allows one to consider models that recognize bias and other effects. Two basic signal detection models, associated with different decision rules, are presented. A version of the covert decisions rule is introduced that directly allows for same–different bias, in contrast to earlier versions. It is shown how to fit the models with standard software for nonlinear mixed models. The models are applied to data from a recent same–different study.     

Effects of Reward Structures on Academic Performance and Group Processes in a Classroom Setting

Researchers have suggested that cooperative, intergroup competitive, and individualistic reward structures result in different patterns of academic performance and group processes. In this study, we investigated these relationships in an undergraduate business school setting. A reward structure was manipulated across four separate classes, and outcomes were measured using self-reports of group effectiveness, academic performance as graded by instructors, and peer evaluations from group members. The results indicated that group effectiveness was rated significantly higher under the cooperative and no-reward conditions compared to the intergroup competitive reward condition. Peer evaluations in the intergroup competitive condition were significantly lower then those under the other three conditions.     

An Inventory of Affective Tolerance

The two dimensions of personality, extraversion (E) and neuroticism (N) as measured by the Eysenck Personality Inventory (EPI), were tested for their social desirability response set and their independence. Results from a collegiate sample (N = 282) show that E and N scales were susceptible to social desirability response bias for males and females, respectively. This bias could not be overcome by eliminating Ss who reported higher scores on the lie scale included in the EPI. The dimensionality of the two scales for the male Ss is questionable.     

From interactions to mental representations: Psychodynamic parent – infant therapy in a case of severe eating and sleep disorders

This paper describes the process of psychodynamic psychotherapy with an infant and his family, during a developmental phase in which the infant's mental organization was in transition from the level of interactions to representations. The treatment of a 23-month-old boy suffering from a severe sleeping and eating disorder was initiated in a parent?–?child psychotherapeutic setting. The sleep disorder was a consequence of separation anxiety. Additionally, phobic avoidance of new oral experiences led to an eating disorder. These symptoms had developed in the context of dysregulation of the triadic family relationships (mother?–?father?–?children), which tended to split into two-plus-one relationships. After one year, the setting was changed to alternating individual and family sessions. Due to his developing symbolic capacities, the boy was able to express his inner concerns and his internalised affect-laden experiences through play and actions. His internal world could now be addressed by interpretations. New psychodynamic theories and research results on early triadic development were taken as the theoretical background for the psychotherapeutic work. We understood the course of the treatment and the development of the transference/countertransference relationships in terms of processes of triadification (at the level of interpersonal relationships) and triangulation (at the level of intrapsychic representations).     

Keeping mother alive: psychotherapy with a teenage mother following human trafficking

The power of new traumatic events to reignite memories and the distress of traumatic experiences earlier in life is well known to psychotherapists. When the recent trauma has been extreme, the task of assisting the patient to understand their response in the light of their earlier experience can be doubly challenging. This paper describes the therapy with an adolescent girl and her infant daughter, following the girl's escape from illegal detention, physical abuse and forced prostitution, after she was trafficked to the UK from Eastern Europe. The discussion works towards developing an understanding of the emotional interchange between the mother and infant, and the influence of the mother's traumatic experiences, on that interchange. Projective identification could be seen to occur from the mother, into her daughter, in a reversal of the situation traditionally described. The function of this for the mother and the impact on the developing infant, are considered.     

Therapeutic action in psychoanalytic therapy with toddlers and parents

Psychotherapy with toddlers and parents can focus on promoting attachment, facilitating development and improving interactions. Some techniques provide guidance to the parents, whereas others interpret to them their unconscious fantasies or ‘ghosts’ contributing to the child’s disorder. A recent paper introduced a psychoanalytically oriented technique, which emphasised the therapist’s interaction with the child in the presence of the parent(s). The child was addressed about his/her unconscious motivations in the session and the feelings towards the therapist. Also, the parent’s transference onto the therapist was seen as a vehicle that might further the therapeutic process and was accordingly addressed. The present paper analyses the therapeutic action in such treatments. Whereas work with the parents resembles that of ordinary psychodynamic therapy, therapeutic action is more difficult to conceptualise regarding the toddler, whose understanding of verbal interpretations and the therapist’s dialogues with the parent is more limited than that of an adult. However, a clinical vignette demonstrates a toddler’s precise and swift reactions to communications from mother or therapist. The paper investigates evidence from neuroscience and psychological research as to which communicative channels – beyond words – toddlers might perceive and comprehend. In addition, it is claimed that the countertransference is key to explaining how the therapist understands such communication.     

Pete the diesel: Psychotherapy with a severely disturbed five-year-old boy

The psychic significance of the figure of the grandmother in psychodynamic psychotherapy has received scant attention. This paper develops the concept of the ‘grandmaternal transference’ in parent–infant psychotherapy and explores its identification, its possible functions and its therapeutic significance. The grandmaternal transference has special relevance to parent–infant psychotherapy since the grandmother often represents both the mother’s mother and the child’s grandmother and offers a unique third position between mother and child. Three clinical vignettes illustrate how the grandmaternal transference may operate in this third position. In the first vignette, the therapist becomes in the transference a containing grandmother thereby facilitating maternal containment. In the second case, the therapist may be experienced as a differentiating grandmother able to help mother and infant with separation and individuation. In the third one, the therapist is transferentially experienced as a paternal grandmother who acts as a pseudo-father able to embody the paternal function. In each of these positions, the transference and countertransference – whether positive or negative – require that the therapist responds to rather than enacts the grandmaternal role. The three configurations of the grandmaternal transference have different clinical manifestations and offer different therapeutic ports of entry.
