False memory for associated word lists in individuals and collaborating groups

Using the Deese/Roediger-McDermott (DRM) paradigm, we investigated recall of presented and nonpresented associated words by collaborating groups, nominal groups, and individuals. In Experiment 1, participants recalled individually and then recalled in collaborating groups. Nominal groups made up of individual recall produced more presented and nonpresented associated words than did collaborating groups. Collaborating groups recalled more presented words than did individuals, but not more nonpresented words. In Experiment 2, collaborating groups versus individuals was a between-subjects variable, and everyone made two recall attempts. For recall, the pattern was the same as that in Experiment 1, in that collaborating groups recalled more presented words than did individuals but about the same number of nonpresented words. In a DRM paradigm, collaborating groups were able to produce more presented words than were individuals, without increasing their false recall.     

A database of associative strengths from the strength-sampling model: A theory-based supplement to the Nelson,McEvoy, and Schreiber word association norms

The strength-sampling model of free association (Nelson, McEvoy, & Dennis, 2000) claims that the probability of word association in free-association norms results from a sampling process. For a given cue word, each response word has an underlying distribution of strength values. In the free-association task, presentation of the cue word activates a random sample of strengths, one for each response. The highest strength wins, and its response is reported. In the present work, gradient descent was used to compute the theoretical mean strengths for each cue-response pair in the Nelson, McEvoy, and Schreiber (2004) norms. The resulting database may be downloaded from www.psychonomic.org/archive/.     

Spatial term apprehension with a reference object’s rotation in three-dimensional space

It has been reported that the overall shapes of spatial categorical patterns of projective spatial terms such as above and below are not influenced by the rotation of a reference object on a two-dimensional (2D) upright plane. However, is this also true in three-dimensional (3D) space? This study shows the dynamic aspects of the apprehension of projective spatial terms in 3D space by detailing how the rotation of a reference object with an inherent front influences the apprehension of projective spatial terms on a level plane by mapping their spatial categorical patterns. The experiment was designed to examine how spatial categorical patterns on a level plane changed with the rotation of a reference object with an inherent front in 3D computer graphics space. We manipulated the rotation of a reference object with an inherent front at three levels (0°, 90°, and 180° rotations) and examined how such manipulation changed the overall spatial categorical patterns of four basic Japanese projective spatial terms: mae, ushiro, hidari, and migi (similar to in front of, behind, to the left of, and to the right of in English, respectively). The results show that spatial term apprehension was affected by the rotation of the reference object in 3D space. In particular, rotation influenced the mae–ushiro and hidari–migi systems differently. The results also imply that our understanding of projective spatial terms on a level plane in 3D space is affected dynamically by visual information from 3D cues.     

Basis of metamemory judgments for text with multiple‐choice,essay and recall tests

Accuracy of metamemory for text was compared for multiple‐choice, essay and recall tests. Essay and recall tests were scored with Latent Semantic Analysis (LSA), number of correct idea units and number of word matches. Each measure was correlated with college students' predictions and posttest confidence judgments across texts to determine metamemory accuracy. Metamemory accuracy varied for different types of tests with multiple‐choice tests generally producing greater accuracy than essay tests. However, metamemory accuracy for essay and recall tests depended on the measure used to score them. Number of correct idea units produced the highest metamemory accuracy, word matches produced an intermediate level, and LSA produced the lowest accuracy. Students used the quantity of output in their judgments, so performance measures that related most strongly to quantity matched judgments better than measures based on answer quality. The results are compatible with an accessibility account of judgments about performance on text. Copyright © 2008 John Wiley & Sons, Ltd.     

The helping orientations inventory: Measuring propensities to provide autonomy and dependency help

Research on helping behavior distinguishes between giving recipients the tools to solve problems for themselves (autonomy‐oriented help) and direct solutions not requiring recipients' involvement (dependency‐oriented help). Across three studies, we examined whether individuals can be characterized by dispositional propensities toward offering autonomy‐oriented and/or dependency‐oriented help. In initial studies, factor analyses revealed the two hypothesized Helping Orientations Inventory scales along with an additional scale capturing opposition to helping, all acceptable in internal consistency and test–retest reliability (Studies 1a–1c). Next, we found that the three scales related in distinct ways to constructs from the intergroup (e.g., social dominance orientation) and interpersonal (e.g., empathic concern) helping literatures (Studies 1d and 1e). Additionally, these orientations predicted satisfaction with volunteer behavior (Study 2) and interest in future volunteering (Study 3). Overall, people vary in their helping orientations, and these orientations implicate a range of variables relevant to intergroup and interpersonal helping.     

Temporal relationships between plasma cortisol, corticosteroid-binding globulin (CBG), and the free cortisol index (FCI) in pigs in response to adrenal stimulation or suppression

The objective of this study was to document changes in plasma concentrations of total cortisol, porcine corticosteroid-binding globulin (pCBG), and the free cortisol index (FCI) in pigs over a 6-h period in response to adrenal stimulation or suppression. Twenty-four 8-week old pigs allotted in equal numbers were administered ACTH, dexamethasone or saline, and blood samples were collected every 15 min via an indwelling jugular catheter for 1 h prior to and 5 h following treatment. Total plasma cortisol increased in ACTH-treated pigs and decreased in dexamethasone-treated pigs within 0.25 and 0.5 h, respectively. In contrast, pCBG concentration was altered in an inverse fashion subsequent to the changes exhibited in total cortisol. FCI reflected the changes observed in total cortisol. These results further document the negative relationship that exists between circulating concentrations of plasma cortisol and pCBG, and illustrate that this association exists under conditions of acute stress in the pig.     

How bilingual experience and executive control influence development in language control among bilingual children

This longitudinal study investigates whether the development in executive control and bilingual experience predicts change in language control in bilingual children. Children were tested twice over the course of 1 year, using the language‐switching paradigm and the Simon task. The participants were Japanese‐English bilingual “returnee” children (ages 7–13), who returned to their first language (L1) environment after spending some years in a second language (L2) dominant environment. Testing these children upon their return to the L1 environment allowed us to disentangle the effect of age from bilingual experience, as they experienced an increase in age but a decrease in L2 exposure over time. Children who had less L2 exposure showed smaller improvement in baseline performance when naming pictures in English (i.e., when English was relevant across all trials). Moreover, development in trials where children had to switch between languages were modulated by development in executive control. That is, children who increased their performance in the English mixed repetition trials also performed better on the executive control task over time. Thus, development in executive control modulated change in language control among bilingual children, suggesting a positive relationship between language control and executive control in children's development.     

The 1994 ACA Model Legislation For Licensed Professional Counselors

Model legislation seeks to facilitate uniformity of counselor licensure laws and promote accepted professional standards. The text of the model bill as endorsed by the 1994 American Counseling Association Governing Council is provided with commentary accompanying those sections in which significant changes have occurred. The article concludes with 15 specific suggestions based on experiences gained in the development and implementation of previous legislation for licensed professional counselors.
