A Dissociation between Symbolic Number Knowledge and Analogue Magnitude Information

Semantic understanding of numbers and related concepts can be dissociated from rote knowledge of arithmetic facts. However, distinctions among different kinds of semantic representations related to numbers have not been fully explored. Working with numbers and arithmetic requires representing semantic information that is both analogue (e.g., the approximate magnitude of a number) and symbolic (e.g., what / means). In this article, the authors describe a patient (MC) who exhibits a dissociation between tasks that require symbolic number knowledge (e.g., knowledge of arithmetic symbols including numbers, knowledge of concepts related to numbers such as rounding) and tasks that require an analogue magnitude representation (e.g., comparing size or frequency). MC is impaired on a variety of tasks that require symbolic number knowledge, but her ability to represent and process analogue magnitude information is intact. Her deficit in symbolic number knowledge extends to a variety of concepts related to numbers (e.g., decimal points, Roman numerals, what a quartet is) but not to any other semantic categories that we have tested. These findings suggest that symbolic number knowledge is a functionally independent component of the number processing system, that it is category specific, and that it is anatomically and functionally distinct from magnitude representations.     

Linkages Between Children's Social and Academic Competence: A Longitudinal Analysis

The relation between social and academic competence was examined in a group of school-age children (N = 163) using structural equation modeling to determine the direction of influence between these two domains across time. A model posing that a reciprocal relation exists between the two domains was tested. The two nested models within the reciprocal model were also tested. To test these models, social acceptance as well as prosocial and aggressive behaviors were assessed by teachers and peers, and children's academic achievement was measured by language and math report-card grades and work skills. Results supported the reciprocal model, indicating that academic achievement directly influenced social competence from both first to second and second to third grade, and social competence was reciprocally related to academic achievement from second to third grade. Implications of these findings for the education process are discussed.     

Parent Expectancies for Child Therapy: Assessment and Relation to Participation in Treatment

Two studies examined parents' pre-treatment expectancies for their child's psychotherapy among children (N = 405, ages 2–15) referred for oppositional, aggressive, and antisocial behavior. Study I focused on the development of a measure to assess expectancies. The results indicated that the measure was internally consistent. Moreover, socioeconomic disadvantage and ethnic minority status, severity of child dysfunction, child age, and parental stress and depression were significant predictors of lower parent expectancies for child therapy. Study II examined the relation of parent expectancies and participation in therapy. The results indicated that parent expectancies predicted subsequent barriers to treatment participation, treatment attendance, and premature termination from therapy. Overall, these findings have implications for the study of expectancies for therapy, for identifying families at risk for premature termination from treatment, and for the development of interventions designed to increase parent participation in child therapy.     

A longitudinal study of the etiology of separation anxiety

A longitudinal examination of the relation between separation experiences and the development of separation anxiety at age 3, 11 and 18 years was conducted. Three associative pathways (Rachman, S.J. (1978). Fear and courage. San Francisco: W.H. Freeman) were assessed. Conditioning events were not related to separation anxiety at age 3. Vicarious learning (modelling) in middle childhood (age 9 years) was the conditioning variable most strongly related to separation anxiety at age 11, accounting for 1.8% of the variance in symptoms. Separation experiences (hospitalisations) before the age of 9 were inversely correlated with separation anxiety at age 18. That is, more overnight hospital stays in childhood were related to less separation anxiety in late adolescence. However, none of these conditioning correlates remained significant predictors of separation anxiety in adjusted regression models. In contrast, certain “planned” separations in early–mid childhood were associated with lower levels of separation anxiety at later ages. Generally, the findings were consistent with predictions from the non-associative theory of fear acquisition. That vicarious learning processes appeared to modulate, albeit to a minor degree, the expression of separation anxiety during mid–late childhood suggests that there may be critical periods during which some individuals are susceptible to the interactive effects of both associative and non-associative processes. These findings serve to illustrate the complexity of fear acquisition, the relevance of developmental factors and the likely interplay between associative and non-associative processes in the etiology of fear and anxiety.     

Punishing Individuals for Their Infirmities: Effects of Personal Responsibility, Just-World Beliefs, and In-Group/Out-Group Status

This research examined how derogation of cancer victims was moderated by (a) the perceived responsibility of the victim, (b) individual differences in just-world beliefs, and (c) whether the victim was an in-group versus out-group member. Participants formed an impression of an in-group or an out-group member who was known to have a terminal case of cancer. Half of the participants were informed that the target person was partially responsible for this medical condition, whereas the remaining participants were not given this information. Results showed that blaming judgments of high versus low responsibility targets were moderated by just-world beliefs, but this was only true when the person being judged was an out-group member. The implications of these results for research and theory on differential processing of in-group versus out-group members are discussed.     

A Note on the Nonlinearity of the Age-Job-Satisfaction Relationship

Research assessing the relationship between age and job satisfaction has typically provided mixed results. Inherent problems including limited samples and a failure to control for tenure and affective disposition have potentially contributed to these conflicting results. Moreover, a significant concern has been researchers' focus on detecting linear effects alone. In the current study, we statistically controlled for gender, supervisor and position tenure, quadratic tenure terms, and affective disposition (NA and PA) based on previous research regarding the relationship between these variables and job satisfaction. Finally, we used hierarchical polynomial regression to assess the form of the age-satisfaction relationship. Results confirmed that a U shape best characterized the relationship between age and job satisfaction. Implications of these findings as well as directions for future research are discussed.     

The Relationship Between Dissociation and Religiosity: An Empirical Evaluation of Schumaker's Theory

Dissociation can be broadly understood as alterations in consciousness where integrated processing of psychological and/or sensory information is disrupted. Following Schumaker's (1995) suggestion that dissociation elicited by religious ritual provides the basis for religious beliefs, the current aim was to empirically assess the relationship between dissociation, religious ritual, and religious beliefs. Four samples with varying levels of religious commitment were administered the Dissociative Experiences Scale, the Francis Scale of Attitude Toward Christianity-short form, and the Maranell Religious Ritual Scale. Dissociation scores were highest in the young Catholic sample and lowest in the Fellowship group. However, these results are largely affected by the covariate of age. No relationship was found between dissociation, religious attitude, and religious ritual in the student sample. However, small to moderate significant correlations were found in the Catholic sample. Results are discussed with reference to Schumaker's theoretical proposal and directions are suggested for future assessment of the dissociation-religiosity relationship.     

Learning: Association or Computation? Introduction to a Special Section

The fundamental nature of learning is a central problem in psychology. Traditionally, psychologists have assumed that learning must involve the formation of associations. Early last century, the pioneering work of Pavlov on conditioned learning in animals seemed to put this assumption beyond doubt. More recently, many psychologists came to believe that a different kind of process must underlie complex learning, such as language learning in humans, and that this process must be described as computational rather than associative. Whether complex human learning is associative or computational continues to be a subject of intense research. The articles in this Special Section turn this debate on its head by asking whether simple animal learning is associative or computational. Surprisingly, the question is still very much open, and excitingly, it appears quite tractable.
