Encoding and output order processes in short-term order recall of distinctive items.

Adults recalled the order of the letters in one of two four-letter segments following a distractor task. They knew in advance the identity of the letters in each segment. A letter was made distinctive by replacing it with a red dash. This unusual form of distinctiveness generally had negative effects on recall of both the segment containing the missing letter and the absent letter within the segment. Encoding and output processes were manipulated by varying precue information and recall order instructions, respectively. Informing participants in advance whether or not a trial would contain a distinctive (i.e., missing) letter depressed recall. Constraining output order eliminated the disadvantage for the absent letter. The results are discussed in terms of encoding and output order processes in short-term recall of order information.     

Staff survey results and characteristics that predict assault and injury to personnel working in mental health facilities

The purpose of this study was to complete a mental health staff opinion survey to identify patient and staff characteristics associated with staff assault and injury in psychiatric treatment settings and to develop a model of prediction for staff assault and injury utilizing these survey variables. The data consisted of opinion surveys sent to staff of 15 child, adolescent, and adult psychiatry inpatient units in the United States. Multivariate logistic regression was used to determine the level of assault and staff‐reported injury prediction that could be obtained from the staff‐completed opinion survey. Responses indicated a high prevalence of reported aggression, with 62.3% of staff endorsing verbal and physical aggression, property destruction, and self‐injurious behavior as being prevalent at their site, whereas only 4.1% rated none of these as prevalent. Staff working with children and adolescents in settings with high rates of psychiatric diagnoses reported increased frequency of assault and injury compared with those working with adults. Younger, less experienced staff reported higher rates of assault and injury. Staff working with female patients reported similar rates of assault and injury to those working with males. A logistic regression analysis using staff‐reported survey results of both staff and patient characteristics predicted assault correctly 73.7% of the time and injury 66.1% of the time. Resources for violence prevention and staff training programs in violence prevention are needed in child and adolescent psychiatry wards. Results are consistent with theories emphasizing the importance of negative emotions and affects, impulsivity, and frustration in goal‐directed activities in human aggression. Aggr.

The internal representation of numbers

A principle of second-order isomorphism asserts that the functional similarities among internal representations parallel the structural similarities among the external objects to which those representations correspond. In accordance with this principle, subjects were asked to rate the similarities of all pairs of the numbers 0 through 9 in each of 24 conditions distinguished by the forms into which they were to be mentally transformed and then judged-including the visual forms of rows of dots and Arabic numerals, the auditory form of spoken English names, and the amodal form of the abstract concepts of the integers themselves. Similarity ratings were found to depend entirely upon the form in which the numbers were to be judged and not at all upon the form in which they were actually presented. Regardless of the form presented, multidimensional scaling solutions for each of the 24 conditions were readily interpretable in terms of structural properties of the form judged-curvature and closure for visual numerals; number of syllables, initial consonant, and vowel phoneme for auditory names; and numerical magnitude, odd-evenness, etc., for abstract concepts. Reanalyses of chronometric data are presented to illustrate how a fuller understanding of human cognitive processes may be attainable by using such structural models of internal representation in conjunction with studies of overt confusion and reaction time.     

A digital system for recording startle,responses in small animals

An easily constructed, isometric startle-recording system is described. The animal enclosure is attached to a plywood board-which, in ten, is mounted in a “springboard” arrangement. Movement is detected by a phonocartridge mounted beneath the chamber, and a digital record of this movement is obtained through the use of a voltage-to-frequency converter. A brief experiment in which the system was used to assess the rat’s reaction to electric footshock is also presented.     

Self-Compassion and Predictors of Criminality

The main focus of this article is to conduct an exploratory investigation of self-compassion, a positive indicator of mental health, as a predictor of violence and criminality within a sample of prisoners. Correlation and regression analyses were used to explore the relationship that self-compassion has with self-control, self-esteem, and social connectedness. Associations between self-compassion and the subscales of self-control were also examined. Results from both correlational analysis and regression indicate that self-compassion is correlated with all 3 variables. Correlations revealed that self-compassion was related to all 6 subscales of self-control. Regression, however, revealed that impulsivity was the only predictor of self-compassion. Further analysis revealed problems with multicollinearity. Implications and limitations of these results are discussed.     

A Self‐Report Measure of Productive Thinking in Solving Insight Problems

There is broad agreement among executives on the importance of innovation and creativity in organizations. The paper aimed to provide information on the effectiveness of a new cognitive style inventory, the Productive‐Reproductive Thinking Inventory (P‐R), in identifying people with creative problem‐solving potential. Participants completed the P‐R Inventory, Kirton's Adaption‐Innovation Inventory (KAI), the Assimilator‐Explorer Inventory, self‐rating of insight problem‐solving, and a battery of insight problem‐solving tasks under controlled conditions. The P‐R scale was a significant predictor of problem‐solving performance and insight self‐ratings and correlated significantly with KAI and AE scores. In addition, the results supported distinguishing two types of reproductive thinking which are differentially associated with insight performance. The distinction was supported by confirmatory factor analysis and structural equation models. Using controlled conditions may limit the generality of the findings and further research should be carried out in applied settings. The P‐R inventory is short and easily administered and may provide HR professionals with a useful screening tool for assessing creative problem‐solving potential. The measure differs from the KAI in several ways that may offer advantages for creativity researchers in that it is non‐proprietary, based on well‐established psychological constructs, and is more particularly applicable to insight problem‐solving.     

You’re looking for what? Comparing search for familiar,nameable objects to search for unfamiliar,novel objects

Searching for items in one’s environment often includes considerable reliance on semantic knowledge. The present study examines the importance of semantic information in visual and memory search, especially with respect to whether the items reside in long-term or working memory. In Experiment 1, participants engaged in hybrid visual memory search for items that were either highly familiar or novel. Importantly, the relatively large number of targets in this hybrid search task necessitated that targets be stored in some form of long-term memory. We found that search for familiar objects was more efficient than search for novel objects. In Experiment 2, we investigated search for familiar versus novel objects when the number of targets was low enough to be stored in working memory. We also manipulated how often participants in Experiment 2 were required to update their target (every trial vs. every block) in order to control for target templates that were stored in long-term memory as a result of repeated exposure over trials. We found no differences in search efficiency for familiar versus novel objects when templates were stored in working memory. Our results suggest that while semantic information may provide additional individuating features that are useful for object recognition in hybrid search, this information could be irrelevant or even distracting when searching for targets stored in working memory.     

Critical reflections on postgraduate andragogy from the points of view of a Kenyan student and an Australian academic

In this paper, we use Critical Reflective Practice to give voice to the experience of a Kenyan teacher who travelled to Australia to undertake advanced coursework in leadership and inclusive education studies. It also reflects upon an Australian academic as she tries to be more culturally responsive in her andragogy when teaching, supervising and mentoring postgraduate international students. We use reflective practices over an extended period to lessen the power imbalance between them as academic supervisor and postgraduate student. This eventually allowed for the student to teach and the academic to learn; and together we here shed light on what it is like to study and teach within an Australian university that annually enrols 6000 students from more than 100 countries around the globe.
