Attributions of Responsibility for Memory Problems in Older and Younger Adults

This study investigated older and younger persons' responsibility attributions for the cause of and solution to a memory problem and, for comparison, a weight problem. Traditional college-age students (n = 116) and persons over 65 years of age (n = 98) read a vignette describing either a 25-year-old or 65-year-old who had a memory or weight problem. Results indicated that both the age of the help-seeker and problem type affected attributions. Specifically, the 65-year-old was perceived to be less responsible than the 25-year-old for the cause of and solution to a memory problem. In addition, help-seekers with a memory problem were held less responsible for causing and solving their problem than were help-seekers with a weight problem.     

The primacy of generalities in hypothetical reasoning

Subjects were given a noncontradictory set of propositions followed by a sentence which they had to accept as true. This sentence introduced an inconsistency which the Ss were required to resolve by assigning truth values to the statements. In previous work, the authors found that when forced to choose between the truth of a generality (All A's are B's) and that of a particular fact (This Y is a Z), subjects consistently rejected the fact in favor of the generality. Affirmative generalities were accepted more often than negative ones, and those expressing class-inclusion were accepted more often than those expressing property-assignment. The present experiments show that preference for generalities is independent of (a) the superficial form of the generality (i.e., the surface presence of a quantifier), (b) the polarity of the contrasted fact (affirmative or negative), and (c) the terms used to express the relations (is a and has a). The preference for reasoning with generalities is enhanced when they assert generally known facts which are not delimited in space or time. A theoretical treatment of the results employing the calculus of modal logic was explored.     

Nonhumans have not yet shown stimulus equivalence

Recently, two published articles have reported finding stimulus equivalence in nonhumans. One suggested that equivalence was due to the mediation of names. The procedure used trained all components of all tested relations. Because nothing was derived, the defining characteristics of equivalence were not achieved. In the second study a definition of equivalence was proposed that fails to distinguish functional stimulus classes from equivalence classes. The resulting data are not clearly relevant to stimulus equivalence in Sidman's sense of the term. Stimulus equivalence has not yet been shown in nonhumans.     

The technical drift of applied behavior analysis

Four dimensions (applied, analytic, general, conceptual) were selected from Baer, Wolf, and Risley's (1968) seminal article on the nature of applied behavior analysis and were monitored throughout the first 10 volumes of the Journal of Applied Behavior Analysis. Each of the experimental articles in Volumes 1 through 6 and the first half of Volumes 7 through 10 was rated on each of these dimensions. The trends showed that applied behavior analysis is becoming a more purely technical effort, with less interest in conceptual questions. We are using simpler experimental designs and are conducting fewer analogue studies. Although concern for maintenance is increasing, other forms of generality are being measured or analyzed less often. These trends are discussed in terms of a technical drift in applied behavior analysis.     

Retrospective assessment of childhood sexual and physical abuse: a comparison of scaled and behaviorally specific approaches

This study compared retrospective reports of childhood sexual and physical abuse as assessed by two measures: the Childhood Trauma Questionnaire (CTQ), which uses a Likert-type scaling approach, and the Computer Assisted Maltreatment Inventory (CAMI), which employs a behaviorally specific means of assessment. Participants included 1,195 undergraduate students recruited from three geographically diverse universities. Agreement was high across the two measures in the classification of victim status (92% and 80% for sexual and physical abuse, respectively). However, the CTQ classified more participants as sexually abused than did the CAMI, whereas the opposite trend was found for physical abuse. For child physical abuse, many participants reporting abusive acts on the CAMI scored below the cut-point for physical abuse on the CTQ. Classification differences for both types of abuse were largely unrelated to demographic factors, socially desirable responding, or self-reported withholding of information. The implications of these results are discussed in light of future research using retrospective methods of assessing childhood abuse.
