Preschoolers’ nonsymbolic arithmetic with large sets: Is addition more accurate than subtraction?

Adult and developing humans share with other animals analog magnitude representations of number that support nonsymbolic arithmetic with large sets. This experiment tested the hypothesis that such representations may be more accurate for addition than for subtraction in children as young as 3½ years of age. In these tasks, the experimenter hid two equal sets of cookies, visibly added to or subtracted from the sets, and then asked 3½-year-olds which set had more cookies. Initial set size was either large (7 or 9) or very large (18 or 30), and the final sets differed by either a high proportion (ratio of 1:2) or a low proportion (difference of 1 cookie). Children’s addition performance exceeded chance, as well as their subtraction performance, across set sizes and proportions, whereas subtraction performance did not exceed chance. Arithmetic performance was also independent of counting ability. Addition performance was remarkably accurate when ratios between outcomes were close to 1, in contrast to previous findings. Interpretations for the asymmetry between addition and subtraction are discussed with respect to the nature of representations for nonsymbolic arithmetic with large sets.     

Context influences holistic processing of nonface objects in the composite task

We explored whether holistic-like effects can be observed for nonface objects in novices as a result of the task context. We measured contextually induced congruency effects for novel objects (Greebles) in a sequential matching selective attention task (composite task). When format at study was blocked, congruency effects were observed for study-misaligned, but not study-aligned, conditions (Experiment 1). However, congruency effects were observed in all conditions when study formats were randomized (Experiment 2), revealing that the presence of certain trial types (study-misaligned) in an experiment can induce congruency effects. In a dual task, a congruency effect for Greebles was induced in trials in which a face was first encoded, but only when it was aligned (Experiment 3). Thus, congruency effects can be induced by context that operates at the scale of the entire experiment or within a single trial. Implications for using the composite task to measure holistic processing are discussed.     

Retirement Resources Inventory: Construction,factor structure and psychometric properties

The scientific investigation of the relationship between resources and retirement well-being is impeded by the lack of proper measurement of resources. This study reports on the development of an inventory that assesses resources relevant to retirement well-being. The 35-item Retirement Resources Inventory (RRI) is a self-report measure consisting of three factors. The RRI was extensively evaluated in a sample of 267 Australian retirees aged 50 years or above. In general, the three subscales of the RRI were shown to possess good internal consistency (0.81–0.89) and test–retest reliability (0.83–0.88) within a one-month interval. Retirement resources, as assessed by the RRI, significantly accounted for additional variance in both retirement satisfaction (16%) and retirement adjustment (22%) above and beyond that explained by demographic variables. More importantly, results from cross-lagged panel analysis indicated that retirement resources predicted retirement well-being rather than the reverse. Findings from the current study provide strong support for the resource perspective, which proposes that resources are critical to well-being in retirement. Theoretical and practical implications of these findings for retirement planning and designing retirement interventions are discussed.     

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.     

Helping Children and Caregivers Cope with Repeated Invasive Procedures: How Are We Doing?

This paper discusses recent developments in the medical and psychological management of child behavioral distress during invasive (i.e., needle stick) procedures for diagnosis and treatment of chronic pediatric disorders. Along with a review of relevant studies from the medical, pediatric psychology and behavior analysis literatures, representative data are presented from recent research on pediatric procedural pain management. The impact of increasing use of implanted subcutaneous intravenous catheters (ports) and decreased reliance on intravenous cannulation is discussed. Similarly, the effects (and limitations) of more frequent use of topical anesthesia to prepare needle sites also are presented. The continuing need for adjunctive, nonpharmacological (i.e., cognitive and behavioral) interventions for procedural pain is emphasized, and recent studies on distraction and counter-conditioning-based treatments are described. Future research is encouraged on (1) behavioral interventions in relation to day-to-day contextual variables that modulate treatment effects and (2) the development of efficient screening measures to identify children and families who are least likely to cope effectively with repeated procedures, allowing them to be given greater priority for allocation of limited resources for psychosocial intervention.     

Group Therapy with Sexually Abused Boys: Leadership,Projective Identification,and Countertransference Issues

Group therapy is an essential component of the treatment of sexually abused children. Since the painful affects associated with the abuse are often dissociated or acted out, the group leaders learn of the affective experience of the abuse through the process of projective identification. The leaders must be aware of this process, set limits on the abusive acting out in the group, and help moderate, label, and empathize with the affect. It is through this difficult process that the children have a chance to reintegrate and work through their abuse experiences so they no longer feel compelled to act them out through repetitive abusive relationships. Specific leadership, countertransference, and projective identification issues in group therapy with sexually abused boys are discussed.     

Symbolic self‐completion in academia: evidence from department web pages and email signature files

Symbolic self‐completion theory proposes that individuals use symbols of attainment to define themselves as accomplished in self‐defining areas and to communicate their accomplishments to others. The goal of the present research was to examine whether individual professors and academic departments strive for symbolic self‐completion when communicating through the Internet. We hypothesized that publications, citations, and departmental rankings by the National Research Council (NRC) represent important indicators of attainment for professors, whereas professional titles (i.e., “doctor,” “professor,” or “Ph.D.”) may serve as alternate symbols of attainment. We predicted that a lack of important indicators of attainment would motivate the display of professional titles in web pages and email signature files. In Study 1, academic departments with less prestigious NRC rankings listed more professional titles on their departmental web pages compared to departments with more prestigious rankings. In Studies 2 and 3, professors with lower annual rates of publications and citations displayed more professional titles in their email signatures compared to professors with higher publication and citation rates. These results suggest that self‐completion motives help to shape naturalistic Internet communications. The results further suggest that analyses of Internet communications can provide externally valid tests of theories concerned with motivation and self‐processes.

Escaping the recent past: Which stimulus dimensions influence proactive interference?

Proactive interference occurs when information from the past disrupts current processing and is a major source of confusion and errors in short-term memory (STM; Wickens, Born, & Allen, Journal of Verbal Learning and Verbal Behavior, 2:440–445, 1963). The present investigation examines potential boundary conditions for interference, testing the hypothesis that potential competitors must be similar along task-relevant dimensions to influence proactive interference effects. We manipulated both the type of task being completed (Experiments 1, 2, and 3) and dimensions of similarity irrelevant to the current task (Experiments 4 and 5) to determine how the recent presentation of a probe item would affect the speed with which participants could reject that item. Experiments 1, 2, and 3 contrasted STM judgments, which require temporal information, with semantic and perceptual judgments, for which temporal information is irrelevant. In Experiments 4 and 5, task-irrelevant information (perceptual similarity) was manipulated within the recent probes task. We found that interference from past items affected STM task performance but did not affect performance in semantic or perceptual judgment tasks. Conversely, similarity along a nominally irrelevant perceptual dimension did not affect the magnitude of interference in STM tasks. Results are consistent with the view that items in STM are represented by noisy codes consisting of multiple dimensions and that interference occurs when items are similar to each other and, thus, compete along the dimensions relevant to target selection.     

The Relationship Between Personal Values and the Perception of the Corporation's Code of Ethics

Most major corporations have instituted codes of ethics to encourage ethical behavior. However, recent studies suggest that these codes are not always effective. One reason that the codes might be ineffective is because the values represented in the code do not correspond with the employee's personal values. The more the code represents values that the individual agrees with, the more positively the employee may view the document. In turn, when the code is viewed positively, transgressions of the code will be viewed negatively. In the present study, employees of a large petrochemical company responded to a survey which solicited their personal values, their perception of the company's values, and their perception of the values behind the organization's code of ethics. In line with the hypothesis, the more similar the values of the code were to the person's values, the more favorable was the evaluation of the code. Similarly the more favorable the evaluation, the more violations of the code were perceived as immoral.
