Isolating observer-based reference directions in human spatial memory: head, body, and the self-to-array axis

Several lines of research have suggested the importance of egocentric reference systems for determining how the spatial properties of one's environment are mentally organized. Yet relatively little is known about the bases for egocentric reference systems in human spatial memory. In three experiments, we examine the relative importance of observer-based reference directions in human memory by controlling the orientation of head and body during acquisition. Experiment 1 suggests that spatial memory is organized by a head-aligned reference direction; however, Experiment 2 shows that a body-aligned reference direction can be more influential than a head-aligned direction when the axis defined by the relative positions of the observer and the learned environment (the "self-to-array" axis) is properly controlled. A third experiment shows that the self-to-array axis is distinct from - and can dominate - retina, head, and body-based egocentric reference systems.     

Validity of a Brief Measure of Parental Affective Attitudes in High-Risk Preschoolers

The current study investigated psychometric properties of the Family Affective Attitude Rating Scale (FAARS) for assessing parents' thoughts and feelings about their child, coded from a 5-min speech sample. Parental affective attitudes derive from previous experiences of parenting and child behavior, representations of the parent-child relationship and broader parental characteristics. Data were collected from mother-child dyads at ages 2 and 3 (N?=?731; 49?% female) from a multi-ethnic and high-risk community sample. Multi-informant observations of parenting and questionnaire measures were used to test construct and discriminant validity. FAARS showed good internal consistency and high inter-rater agreement. Affective attitudes were related to mothers' perceptions of their daily hassles, their reports of conflict with their child, and observed measures of positive and harsh parenting. Negative affective attitudes uniquely predicted later child problem behavior, over and above maternal reports of and observed measures of parenting. Overall, results support the validity of FAARS coding in mothers of preschoolers, a previously untested group. FAARS is a novel measure, directly assessing maternal perceptions of the parent-child relationship, and indirectly providing an index of maternal affect, stress, and depressive symptoms. Its brevity and cost-effectiveness further enhance the potential use of the FAARS measure for clinical and research settings.     

Infant long-term memory for associations formed during mere exposure

We previously found that young infants spontaneously associate stimuli that they merely see together. Using a sensory preconditioning paradigm with 6- and 9-month-olds, we asked how long such associations remain latent before being forgotten and what exposure conditions affect their persistence. Groups were preexposed to two puppets for 1 h/day for 2 days, 1 h on 1 day, or 1 h on 1 day in two sessions; 1-27 days later, target actions were modeled on one puppet, and infants were tested with the other puppet 1 day later. The longest delay after which infants imitated the actions on the other puppet defined how long they remembered the association. The data revealed that the preexposure regimen determined retention. Regardless of exposure time, both ages remembered the association longer after two sessions, and younger infants remembered longer than older infants - for 4 weeks - after two 30-min sessions on 1 day.     

Therapeutic alliance and weight gain during cognitive behavioural therapy for anorexia nervosa

This study examined the relationship between therapeutic alliance and primary symptom change (weight gain) during CBT for anorexia nervosa. The aims were threefold: (1) to establish the strength of the therapeutic alliance across the treatment, (2) to determine whether early therapeutic alliance is associated with the completion of CBT for this client group, and (3) to determine the direction of the relationship between therapeutic alliance and weight gain. Adult outpatients (N = 65) with a diagnosis of anorexia nervosa (or atypical anorexia nervosa) completed a measure of alliance at session six and at the end of treatment. Weight was recorded at the start of treatment, session six and at the end of treatment. The strength of the alliance was consistently high in the sample. However, early therapeutic alliance was not associated with either the likelihood of completing treatment or subsequent weight gain. In contrast, both early and later weight gain were associated with the strength of subsequent alliance. These findings indicate that it might be advisable to focus on techniques to drive weight gain rather than rely on the therapeutic alliance to bring about therapeutic change.     

Carving nature at its joints: Paul Meehl's development of taxometrics

This article presents a brief summary of Paul Meehl's development of taxometrics. Of special concern is the question, Why did Paul Meehl develop taxometrics? It is shown that taxometrics played an integral role in Meehl's broader research program on the genetics of schizotaxia.     

Egocentric and nonegocentric coding in memory for spatial layout: Evidence from scene recognition

Much contemporary research has suggested that memories for spatial layout are stored with a preferred orientation. The present research examined whether spatial memories are also stored with a preferred viewpoint position. Participants viewed images of an arrangement of objects taken from a single viewpoint and subsequently were tested on their ability to recognize the arrangement from novel viewpoints that had been translated in either the lateral or the depth dimension. Lateral and forward displacements of the viewpoint resulted in increasing response latencies and errors. Backward displacement showed no such effect, nor did lateral translation that resulted in a centered "canonical" view of the arrangement. These results further constrain the specificity of spatial memory, while also providing some evidence that nonegocentric spatial information is coded in memory.     

Orientation specificity and spatial updating of memories for layouts

This article examines the degree to which knowledge about the body's orientation affects transformations in spatial memory and whether memories are accessed with a preferred orientation. Participants learned large paths from a single viewpoint and were later asked to make judgments of relative directions from imagined positions on the path. Experiments 1 and 2 contribute to the emerging consensus that memories for large layouts are orientation specific, suggesting that prior findings to the contrary may not have fully accounted for latencies. Experiments 2 and 3 show that knowledge of one's orientation can create a preferred direction in spatial memory that is different from the learned orientation. Results further suggest that spatial updating may not be as automatic as previously thought.     

Perceptions of intergenerational communication across cultures: an Italian case

406 Anglo-American, Italian-American, and Italian (Northern and Southern Italy) students were asked to evaluate past conversations with same-age peers, i.e., 17 to 30 years, and older adults, i.e., 65 years and older. While according older adults more deference, all cultural groups perceived older adults as more rigid and nonaccommodating than younger adults. Exchanges with older adults were reported as having more negative affect than were those with other young adults, and were also more likely to he avoided.
