Short-term memory for spatial and temporal information

Two experiments examined the probed recall of visually presented letter sequences in which the items appeared at different spatial locations. Three types of probe were compared: (1) spatial position; (2) temporal association; and (3) combined position and association. In the first experiment, in which the spatial locations of the items were correlated with their temporal order, spatial probes were more effective than temporal association probes. In the second experiment spatial location was uncorrelated with temporal order, and spatial probes were less effective than temporal association probes. Regardless of the probe, errors tended to be items presented close in time to correct responses: spatial proximity was far less important. The results are discussed in terms of a storage system in which items and their spatial locations are organized within a temporal format. Both experiments showed superior combined probe performance, demonstrating that short-term retrieval is not limited to the use of one type of cue at a time. Secondary aspects of the results showed additionally that subjects can “edit” their responses to avoid making obvious mistakes, and that spatial location can be partially forgotten rather than being completely lost.     

Optimierung expositionsbasierter Therapie

Exposure is an effective approach for treating anxiety disorders, although a substantial number of individuals fail to benefit or experience a return of fear. Research results suggest that anxious individuals show deficits in the mechanisms underlying exposure therapy, such as inhibitory learning. Targeting these processes may help improve the efficacy of exposure; however, there has been little discussion of how to implement this model in clinical practice. The primary aim of this paper is to provide examples to clinicians for how to apply this model to optimize exposure therapy, in ways that distinguish it from a fear habituation approach and a belief disconfirmation approach. Optimization strategies include (1) expectancy violation, (2) deepened extinction, (3) occasional reinforced extinction, (4) removal of safety signals, (5) variability, (6) retrieval cues, (7) multiple contexts and (8) affect labeling. Case studies illustrate methods of applying these techniques with a variety of anxiety disorders.     

Therapists’ experiences with internal representations of clients

Fourteen therapists were interviewed via telephone regarding their experience of “carrying around” their clients with them between sessions (i.e. internal representations, or IRs, of clients), a phenomenon about which little empirically based knowledge exists. Data were analyzed using consensual qualitative research. Findings indicated that overall, therapists have IRs infrequently, most often have IRs of clients struggling with severe or challenging presenting problems, and do receive some training about IRs. When describing a specific IR experience, therapists typically noted a strong therapy relationship, and stated that the IRs typically had specific triggers. The IRs generally consisted of feelings about the client, and typically consisted of thoughts about the client or the felt presence of the client. The IRs generally yielded positive effects, typically both personally and professionally, and were typically discussed with supervisors/consultants. Implications for research, training, and practice are presented.
