Recall in preschool children

Free recall, cued recall, color recall, organization in recall, and sorting of 3- and 4-year-olds was assessed on 9-item lists of objects that were orthogonally varied on color and category dimensions. Half of the children in each age group were presented items successively, and the other half simultaneously. Older children recalled more items than younger children in both free and cued recall, and also organized their recall more. Moreover, simultaneous presentation benefited the older, but not younger children. Clustering and sorting data suggested a decreasing reliance on perceptual information, and increasing utilization of conceptual information, over the preschool years. The results were discussed in terms of the importance of concrete, external stimulus support at both time of encoding and retrieval.     

Paralinguistic aspects of auditory comprehension in aphasia.

Eight severe aphasics were given sentences with either emotional or neutral content, presented once directly by the examiner and once via a tape recorder. Sentences with emotional content produced a greater number of responses than their neutral counterparts. Sentences spoken by the examiner also produced a significantly greater number of responses than the same items originating from a tape recorder. These results confirm the view that elements not related to the linguistic aspects of a message (and therefore referred to as paralinguistic) play a significant role in auditory comprehension.     

Suggestibility and type of interpersonal relationship: Special implications for the patient-practitioner relationship

Suggestibility was assessed in five conditions by the subject's response to suggestions falsely labeled as matters of fact. These misrepresentations of fact, or virtual suggestions, denoted a variety of hallucinations, an anesthesia, and an amnesia. They were administered as incidental intrusions while the subject was involved in the primary experimental task. In three of these conditions, the subject either observed his own spontaneous visual imagery, observed visual scenes provided by the experimenter, or simply waited with closed eyes for the presentation of the virtual stimuli. These conditions were characterized by a passive-receptive, interpersonal relationship in which the subject remained silent. Suggestibility was expected to be high. In a fourth condition the subjects described spontaneous visual imagery. This was characterized as an active-receptive relationship in which speech was maintained throughout. The suggestibility of the three passive-receptive conditions was comparable, and none of them differed from a baseline condition involving the formal induction of hypnosis. However, the fourth, active-receptive condition was significantly lower, and this difference survived a replication. Of special interest was the induction of an anesthesia in the majority of subjects in the three passive-receptive conditions.     

Behavioral confirmation in social interaction: From social perception to social reality

A perceiver's actions, although based upon initially erroneous beliefs about a target individual may channel social interaction in ways that cause the behavior of the target to confirm the perceiver's beliefs. To chart this process of behavioral confirmation, we observed successive interactions between one target and two perceivers. In the first interaction, targets who interacted with perceivers who anticipated hostile partners displayed greater behavioral hostility than targets whose perceivers expected nonhostile partners. Only when targets regarded their actions as reflections of personal dispositions did these behavioral differences in hostility persevere into their subsequent interactions with naive perceivers who had no prior knowledge about them. Theoretical implications of the behavioral confirmation construct for social perception processes are discussed.     

Homily at the Opening Prayer of the 11th Assembly of the World Council of Churches

This is the text of the homily at the opening prayer of the 11th Assembly of the World Council of Churches on 31 August 2022. The homily was based on Jesus' encounter with the Samaritan woman at the well, a narrative in the fourth chapter of the Gospel of John. Despite wide gaps of religious belief, gender, culture, and lifestyle, Jesus took the woman seriously and spoke to her on a personal level.     

Partial reinforcement and autoshaping of the pigeon's key-peck behavior

Pigeons were exposed to continuous and partial reinforcement (25%) schedules in an autoshaping procedure. The number of trials and/or pairings per session were equated across two factorial group sets and all groups were trained for a fixed total number of acquisition trials (192). When acquisition was analyzed as a function of reinforcements delivered, the groups receiving fewer number of trials per session acquired the response faster, independently of the percentage of reinforced trials. Moreover, the number of reinforcements to satisfy an acquisition criterion was a monotonic function of the number of trials per session but not of the schedule. The results are discussed in relation to the neocontinuity and the scalar expectancy theories.     

Apparent impropriety and procedural fairness judgments

Variation in decision making and allocation procedures has been shown to affect judgments of the fairness of the procedure and its outcome, but such effects have always been studied in the context of properly enacted procedures. It was hypothesized that the appearance of impropriety in the enctment of a fair procedure would increase the extent to which the procedure is judged in terms of its outcome. One hundred twenty undergraduate males and females were placed in the role of either defendant or observer with respect to an adversary procedure trial. Appearance of impropriety was manipulated during the trial by either including or not including evidence of a friendly personal relationship between the judge and the plaintiff's lawyer. The defendant was said to have either won or lost the case. A significant impropriety × outcome interaction on ratings of procedural fairness, unqualified by higher order effect, supported the hypothesis: a favorable outcome increased and an unfavorable outcome decreased the fairness of the procedure more when the impropriety was present. Discussion focuses on the implications of these findings for future investigation and theory on procedural justice and for practical issues.     

Statistical analysis of binary relational data: Parameter estimation

Binary interaction data, measuring the presence or absence of a relation between pairs of actors in a “dyadic interaction situation,” are commonly gathered to study the social structure of the group of actors. Recent developments have made the statistical analysis of such data statistically easier and more substantively sophisticated. These developments allow researchers to simultaneously study several sociometric structural properties, such as reciprocity, differential popularity, and equivalence of actors. Building on this research, we review the stochastic models responsible for this breakthrough, and discuss methods for estimating expected values and model parameters. Throughout, we also highlight recent advances designed to incorporate nodal or actor attribute data into the relational data analysis. We conclude with an example illustrating these ideas based on conversational activities among actors in a group of eight people.
