Haptic search is more efficient when the stimulus can be interpreted as consisting of fewer items

In a typical haptic search task, separate items are presented to individual fingertips. The time to find a specific item generally increases with the number of items, but is it the number of items or the number of fingers that determines search time? To find out, we conducted haptic search experiments in which horizontal lines made of swell paper were presented to either two, four or six of the participants' fingertips. The task for the participant was to lift the finger under which they did not feel (part of) a line. In one of the conditions separate non-aligned lines were presented to the fingertips so that the number of items increased with the number of fingers used. In two other conditions the participants had to find an interruption in a single straight line under one of the fingertips. These conditions differed in the size of the gap. If only the number of items in the tactile display were important, search times would increase with the number of fingers in the first condition, but not depend on the number of fingers used in the other two conditions. In all conditions we found that the search time increased with the number of fingers used. However, this increase was smaller in the single line condition in which the gap was large enough for one finger to not make any contact with the line. Thus, the number of fingers involved determines the haptic search time, but search is more efficient when the stimulus can be interpreted as consisting of fewer items.     

Overconfidence in Probability and Frequency Judgments: A Critical Examination

The overconfidence observed in calibration studies has recently been questioned on both psychological and methodological grounds. In the first part of the article we discuss these issues and argue that overconfidence cannot be explained as a selection bias, and that it is not eliminated by random sampling of questions. In the second part of the article, we compare probability judgments for single events with judgments of relative frequency. Subjects received a target individual's personality profile and then predicted the target's responses to a series of binary questions. One group predicted the responses of an individual target, while a second group estimated the relative frequency of responses among all target subjects who shared a given personality profile. Judgments of confidence and estimates of relative frequency were practically indistinguishable; both exhibited substantial overconfidence and were highly correlated with independent judgments of representativeness.     

Self-Construal and Forgiveness Revisited: Replication and Extension

Evidence suggests that people who have greater interdependent self-construal forgive others more often because they are motivated to forgive to maintain the relationship. Furthermore, such forgiveness might lead to greater emotional well-being. In this study, we examined the relationship between interdependent self-construal and (a) decisional forgiveness and (b) emotional well-being. We also tested models that included trait forgivingness and the motivation to forgive to maintain relationships. Results indicated that (a) trait forgivingness and relational motivations to forgive uniquely mediate the relationship between interdependent self-construal and decisional forgiveness and (b) trait forgivingness may be a pathway from interdependent self-construal to emotional well-being.     

Countertransference as compromise formation

Countertransference is a ubiquitous phenomenon, a set of compromise formations comprising the analyst's transference to the patient(s). Some consequences of this fact are discussed, including the factors responsible for those instances when countertransference impedes analysis.     

Notes on psychoanalysis by a participant observer: a personal chronicle

Experience has shown how difficult it may be to decide which ideas are of passing interest and relatively little value and which are more important and fruitful. Examples of each are given in the form of a personal memoir. Some thoughts are added about the present and the future from the same vantage point.     

From acting out to verbalization

This paper examines acting out phenomena through different theoretical perspectives from the past to the present. Using case examples of child and adult patients, the author demonstrates how acting out can be viewed as an opportunity to observe what was pre-verbal and repressed in a patient's life history. Symbolism is seen as the bridge between action and language as well as between patient and therapist.
