Information and the memory span

Messages differing in number of symbols and symbol information load were presented tachistoscopically to 4 adult Ss. The messages were constructed by random drawing with replacement from an alphabet of 8 black form symbols and an alphabet of 32 colored form symbols. The number of symbols recalled varied as a function of alphabet; however, the information in recall was constant for all conditions. The number of symbols recalled and the information in recall was independent of message length.     

Memorabeatlia: A naturalistic study of long-term memory

Seventy-six undergraduates were given the titles and first lines of Beatles' songs and asked to recall the songs. Seven hundred and four different undergraduates were cued with one line from each of 25 Beatles' songs and asked to recall the title. The probability of recalling a line was best predicted by the number of times a line was repeated in the song and how early the line first appeared in the song. The probability of cuing to the title was best predicted by whether the line shared words with the title. Although the subjects recalled only 21% of the lines, there were very few errors in recall, and the errors rarely violated the rhythmic, poetic, or thematic constraints of the songs. Acting together, these constraints can account for the near verbatim recall observed. Fourteen subjects, who transcribed one song, made fewer and different errors than the subjects who had recalled the song, indicating that the errors in recall were not primarily the result of errors in encoding.     

False memories of childhood experiences

We conducted two experiments to investigate if college students would create false memories of childhood experiences in response to misleading information and repeated interviews. In both experiments we contacted parents to obtain information about events that happened to the students during childhood. In a series of interviews we asked the students to recall the parent-reported events and one experimenter-created false event. In the second experiment we varied the age at which we claimed the false event occurred. In both experiments we found that some individuals created false memories in these circumstances and in the second experiment we found no effect of age of attempted incorporation. In the second experiment we also found that those who discussed related background knowledge during the early interviews were more likely to create a false recall. Generalizations to therapy contexts are discussed.     

Normative data for the selective reminding test: a random digit dialing sample

Healthy control participants (46 women, M age=44.3 yr., SD=7.6; 29 men) were recruited to undergo a comprehensive neuropsychological battery and serve as a comparison group in a study of cognitive functioning in patients with Lyme isease. Participants were selected using Mitofsky-Waksberg random digit dialing. The Buschke 12-word, six-trial Selective Reminding Test was administered as part of the neuropsychological battery and normative data are presented stratified by age and sex. Performance on alternate forms of this measure were examined. Mean education, intelligence quotient, and Wide Range Achievement Test-3 Reading scores are reported.     

A Psychotherapy of Schizophrenia: Direct Analysis by Albert E. Scheflen

This article studies the impact of outpatient group therapy on medical care at a large city–county hospital. Of the 65 group therapy outpatients, 33 persons met the criterion of having attended at least 12 group sessions over the course of a year. We compared a control period (the year prior to initiating group therapy) with a study period (months 6–18 after starting group) and found a sharp decrease in the number of hospitalizations and in-hospital days. There was significantly increased use of neuroleptics and nonpsychotropics and increased attendance at nonpsychiatric clinics.     

The Neurobiology of Addiction: Implications for Voluntary Control of Behavior

There continues to be a debate on whether addiction is best understood as a brain disease or a moral condition. This debate, which may influence both the stigma attached to addiction and access to treatment, is often motivated by the question of whether and to what extent we can justly hold addicted individuals responsible for their actions. In fact, there is substantial evidence for a disease model, but the disease model per se does not resolve the question of voluntary control. Recent research at the intersection of neuroscience and psychology suggests that addicted individuals have substantial impairments in cognitive control of behavior, but this “loss of control” is not complete or simple. Possible mechanisms and implications are briefly reviewed.     

Patterns of interprofessional conflict resolution on school child study teams

This study proposes to investigate perceived and desired methods of conflict resolution by school psychologists, social workers, and learning disability specialists. Data were based on responses to a questionnaire which requested information on how decisions were reached or should have been reached when their child study teams were required to classify a child and there were conflicting opinions between professional groups. While majority vote and resolution by the psychologist accounted for the methods most often used in actual resolutions, there were great disagreements between professions as to how resolutions should have been made. Analysis indicates that the school psychologists are generally satisfied because they are the single group most often making final decisions, but they are generating feelings of discontent among other the other groups which suggst that team functioning and decision making, especially during voting, may be overly affected by interprofessional rivalry rather than objective data.
