Schreber'sMemoirs: Myth or personal lamentation

Lucy Bregman's approach to Schreber'sMemoirs is scrutinized and found to be based on a number of fallacious and contradictory assumptions that call her interpretation of the book as personal religious myth into question. A social constructionist approach to mythology maintained by Berger and Luckmann is advanced, suggesting that at best Schreber's work qualifies as a quasi-mythical attempt to explain the source of his personal sociopsychic suffering. The family and interpersonal dynamics of Schreber's quasi-myth are investigated. Similarities to other cases of psychotic quasi-myths are noted and a general relationship between oppressive socialization and psychotic communications is advanced, as well as a specific alternative interpretation of Schreber's work to that proposed by Bregman.Nathan Church, M.S., is currently teaching at Douglass College of Rutgers University, where he is nearing completion of his Ph.D. in sociology.     

Effects of a token reinforcement system on journal reshelving

A token reinforcement program involving two levels of token value and backup reinforcers to increase journal reshelving behavior in a large university library was experimentally evaluated. Results showed that instructions (in which signs asked users to reshelve journals) had no impact. By contrast, token reinforcement contingent on reshelving behavior led to a marked increase in journals reshelved. A return to instructions-only conditions, when data were corrected for library usage, showed an increase in unreshelved journals over the token reinforcement period, though the increase was not to baseline levels. For the next 11 months, library staff maintained a modified token program. Follow-up data collected after that interval showed that number of unreshelved journals remained markedly lower than levels at baseline and the first instructions-only period, though they were slightly higher than at the token reinforcement period. Token reinforcement of the variety employed in this study constitutes an efficient, economical means of changing the behavior of library users who fail to reshelve books and journals.     

Differences in the search rate of children and adults in short-term memory

When people recognize a test item as belonging or not belonging to a previously presented set, recognition latency increases with the number of items in the set. Although some evidence suggests otherwise, it is currently held that the rate of this increase is the same for children and adults. In contrast, the present experiments indicated a much slower search rate for second graders (mean age = 7.33 years) than for seventh (mean age = 12.50 years) and twelfth graders (mean age = 17.25 years). Moreover, search rate for second graders was invariant under instructions which did or did not emphasize speed and with presentation of the memory set in either the auditory or visual modality. Experiment II showed that the slow search rate for children was not due to differences in encoding between children and adults.     

A Taxonomy of Part-Whole Relations

A taxonomy of part-whole or meronymic relations is developed to explain the ordinary English-speaker's use of the term “part of” and its cognates. The resulting classification yields six types of meronymic relations: 1. component-integral object (pedal-bike), 2. member-collection (ship-fleet), 3. portion-mass (slice-pie), 4. stuff-object (steel-car), 5. feature-activity (paying-shopping), and 6. place-area (Everglades-Florida). Meronymic relations ore further distinguished from other inclusion relations, such as spatial inclusion, and class inclusion, and from several other semantic relations: attribution, attachment, and ownership. This taxonomy is then used to explain cases of apparent intransitivity in merological syllogisms, and standard form syllogisms whose premises express different inclusion relations. The data suggest that intransitivities arise due to equivocations between different types of semantic relations. These results are then explained by means of the relation element theory which accounts for the character and behavior of semantic relations in terms of more primitive relational elements. The inferential phenomena observed are then explained by means of a single principle of element matching.     

Conceptualizing Self-determination from a Behavioral Perspective: The Role of Choice,Self-control,and Self-management

The goal of education can be defined in many ways; but in searching the literature, we found that in most cases, people consider the goal of education to be developing a self-determined individual. Self-determination is an abstract term. Behavior analysts may find this term difficult to define. Therefore, it may be difficult to observe and measure whether “self-determined behaviors” have developed. Many other service providers use this term frequently; thus, behavior analysts working with these service providers must come to terms with this concept in order to better collaborate. We argue that self-determination can be operationally defined with the concepts of choice, self-control, and self-management. By using the measurable behaviors included in these concepts, we believe that services can be developed to teach self-determination skills. This paper explores these concepts and how they can contribute to an operational definition of self-determination, and ultimately, help behavior analysts work with other providers to effectively teach self-determination to individuals with developmental disabilities.

     

Inhibitory control and set shifting describe different pathways from behavioral inhibition to socially anxious behavior

Individuals with a behaviorally inhibited (BI) temperament are more likely to develop social anxiety. However, the mechanisms by which socially anxious behavior emerges from BI are unclear. Variation in different forms of top‐down control, specifically executive functions (EF), may play distinct roles and characterize differential pathways to social anxiety. Here 291 children were assessed for BI in toddlerhood (ages 2 and 3), parent‐reported inhibitory control and set shifting during middle childhood (age 7), and multidimensional assessment of socially anxious behavior completed during late childhood and early adolescence (ages 9 and 12). Structural equation modeling revealed that early variation in BI predicted the development of socially anxious behavior through either higher levels of parent‐reported inhibitory control or lower levels of parent‐reported set shifting. These data reinforce the notion that top‐down control does not uniformly influence relations between temperament and socially anxious behavior. These data suggest novel approaches to thinking about the role of EFs and social anxiety outcomes as children approach adolescence.     

Moderating Loss Aversion: Loss Aversion Has Moderators,But Reports of its Death are Greatly Exaggerated

Loss aversion, the principle that losses impact decision making more than equivalent gains, is a fundamental idea in consumer behavior and decision making, though its existence has recently been called into question. Across five unique samples (N_total = 17,720), we tested several moderators of loss aversion, which supported a preference construction account. Across studies, more domain knowledge and experience were associated with lower loss aversion, though people of all knowledge and experience levels were loss averse. Among car buyers, those who knew more about a particular car attribute (e.g., fuel economy) were less loss averse for that attribute but not other attributes (e.g., comfort), consistent with the idea that people with less attribute knowledge are more likely to construct preferences, thereby increasing loss aversion. Additionally, older consumers were more loss averse across different loss aversion measures and studies. We discuss implications for several accounts of loss aversion, including accounts rooted in status quo bias, emotion, or ownership. In addition to discovering loss aversion moderators, we cast doubt on recent claims that loss aversion is a fallacy or is fully explained by status quo bias, risk aversion, or the educated laboratory samples often used to study loss aversion.     

The relationship of perinatal birth status to handedness: A prospective study

As part of a longitudinal study of the consequences of high risk birth, 66 infants born to right-handed parents were given two unimanual tasks at 24 months of age to assess their hand preference. The 66 infants had been assigned to one of four diagnostic categories at birth: Premature with no postnatal medical complications; premature and having experienced respiratory distress; term and having experienced birth asphyxia during labor and delivery; term with normal delivery and postnatal course. Results of the handedness tasks revealed an increased incidence of use of the left hand among the term infants who underwent birth asphyxia and among the healthy preterm infants. The data indicate that timing of birth stress may play an important role in the ontogeny of pathological left-handedness.
