Increasing correct identifications by children

Four new lineup procedures were examined with the goal of increasingchildren's identification accuracy. Participants (329 children aged 10 and11 years, 426 children aged 12 to 14 years, and 265 adults) were presentedwith either a target-present or target-absent lineup. Proceduralmodifications included providing a salient "I don't know" response option,extending standard instructions, and modeling correct responses eitherusing an identification demonstration video or a handout. These conditionswere compared to a standard (control) lineup procedure. Extendingstandard instructions increased correct identifications by the youngerchildren. Presenting a salient "I don't know" response increased overallchoosing for both target-present and target-absent lineups. Experimentalprocedures did not influence correct rejection rates. These data demonstratea variety of techniques that may be useful for improving the identificationaccuracy of child witnesses. Future directions are discussed.     

Guilt and self-concept in ‘secondary psychopaths’

Thirty-two male and 25 female ‘secondary psychopaths’ and 24 male and 24 female ‘normal’ subjects filled in semantic differential scales relating to the concepts: Myself as I am, Myself when I lie, Myself if I were to steal, Myself as I would like to be, People who lie and People who steal. The Mosher Morality-Conscience Guilt scale and the Eysenck Personality Inventories were also administered. The psychopaths exhibited significantly higher Guilt scores than the normal subjects and had very poor self-image which was reflected in a constant feeling of guilt, regardless of whether or not they were rating transgression. Normal subjects, on the other hand, only rated themselves as feeling guilty when they violated acceptable norms. The findings suggest that guilt in ‘secondary psychopaths’ is partly related to their high level of trait anxiety and partly to their poor self-concept which may be a reflection of their disturbed family background and the constant disapproval that their behaviour creates. Since guilt in the psychopaths did not markedly increase with transgression it is argued that this may explain why guilt fails to inhibit unacceptable behaviour in some psychopaths.     

Categorization of Ambiguous Sentences as a Function of a Changing Prosodic Parameter: A Dynamical Approach

The present study investigates the dynamics of changes in interpretation of ambiguous sentences. The sentences used had alternative interpretations with different surface structures (bracketing). Continua were created by systematic manipulation of prosodic cues (relative foot duration), resulting in stimulus sentences that spanned the range between the two interpretations. Continua were presented to subjects who were requested to indicate as quickly as possible which meaning they perceived. The pattern of responses and response times revealed the presence of hysteresis. That is, when the values of prosodic parameters are congruent with both interpretations, the individual's recent history decides which meaning will be perceived. Thus, we can treat this categorization process as a transition from an initially stable meaning that loses stability with variations in prosody (our control parameter). The same underlying dynamics have been observed in studies of perception of syllables and aspects of visual perception. Apart from demonstrating the same characteristics of pattern formation at various levels of cognition, the study points to the usefulness of the dynamical approach in the investigation of language understanding.     

Recognition vs recall of visually vs acoustically confusable letter matrices

In an attempt to separate auditory and visual components in short-term memory, five subjects were exposed to letter matrices composed of six visually confusable letters, six acoustically confusable letters, or a mixture of the two, under two response conditions: recognition and recall. A 50-msec stimulus presentation was followed by a variable dark interval of 1, 250, 1,000, or 3,000 msec. In the recall condition, the interval was followed by a buzzer which signaled the subject to recall, in any order, as many letters as possible. In the recognition condition, the variable interval was followed by a second letter matrix which was either identical to the first matrix or differed from is by one letter. Subjects responded either "same" or "different." The results support the notion that the auditory component plays a major role in recall, whereas the visual component dominates in recognition.     

Treatment of juvenile offenders: Study outcomes since 1980

Past reviews of the treatment of juvenile offenders have concluded that “nothing works.” More recently, some reviewers have concluded that treatment concepts are not necessarily ineffective, but, instead, research methodology and treatment integrity have been inadequate. The present review looks at the treatment of adjudicated juvenile offenders from a computer-data-based search of the literature published from 1980 to 1987. Research outcome and methodology are summarized and critiqued. The conclusions are that treatment outcomes were positive, but that serious methodological weaknesses still exist in the literature. Improvements still need to be made in sample sizes, use of appropriate and multiple measures of recidivism, random assignment and/or use of appropriate control groups, and long-term follow-up assessment.     

The effect of enactment upon sentence imitation in preschool children

Preschool children imitated two matched lists of sentences varying in length, in syntactic complexity, and in semantic complexity. Sentences on one list were acted out with toys prior to imitating them. For 3-year-olds, enactment increased retention of all sentential variables: number of words, number of frames, number of propositions, and syntax. For children younger than 3 years, enactment increased only the number of words retained, while for children older than 4 years, enactment had a minimal effect on all sentential variables. In a second experiment, prior enactment had long-term effects on the degree to which children's spontaneous stories about the toys resembled the previous sentences that they had been given to imitate. Long-term effects, however, did not extend to retention of syntax. Enactment appears to increase both young children's interest in a sentence imitation task and the amount of semantic encoding in which they engage. Its effect, however, is mediated by the degree of mastery of relevant linguistic rules.Some of these data were presented at the Biennial Meeting of the Society for Research in Child Development, Detroit, April 1983. The authors would like to thank Lorraine Chiasson, Judith Codd, and Susan Saba for their assistance with the data analysis.     

Academic cheating as a function of defense mechanisms and object relations

This study examined relationships between academic cheating behaviors by using self-reports of past cheating behavior, providing a situational experiment with the opportunity to cheat, and evaluating defense mechanisms and object relations as measured by the Defense Mechanisms Inventory. Subjects included 75 female and 8 male university students ranging in age from 18 to 51 years (M=25.5, SD=6.9). Analysis showed variations in students' self-reported cheating history relative to their measured object relations status and type of defense mechanisms. Actual cheating in the experimental setting was not significantly related to any of these variables. Findings are discussed based on a critique of heterogeneity of the cheating construct.     

Mechanisms of mindfulness: emotion regulation following a focused breathing induction

The current study investigated whether a 15 min recorded focused breathing induction in a normal, primarily undergraduate population would decrease the intensity and negativity of emotional responses to affectively valenced picture slides and increase willingness to remain in contact with aversive picture slides. The effects of the focused breathing induction were compared with the effects of 15 min recorded inductions of unfocused attention and worrying. The focused breathing group maintained consistent, moderately positive responses to the neutral slides before and after the induction, whereas the unfocused attention and worry groups responded significantly more negatively to the neutral slides after the induction than before it. The focusing breathing group also reported lower negative affect and overall emotional volatility in response to the post-induction slides than the worry group, and greater willingness to view highly negative slides than the unfocused attention group. The lower-reported negative and overall affect in response to the final slide blocks, and greater willingness to view optional negative slides by the focused breathing group may be viewed as more adaptive responding to negative stimuli. The results are discussed as being consistent with emotional regulatory properties of mindfulness.     

Three steps to open science for qualitative research in psychology

Principles and applications of open science (also referred to as open research or open scholarship) in psychology have emerged in response to growing concerns about the replicability, transparency, reproducibility, and robustness of psychological research alongside global moves to open science in many fields. Our objective in this paper is to inform ways of collectively constructing open science practices and systems that are appropriate to, and get the best out of, the full range of qualitative and mixed-method approaches used in psychology. We achieve this by describing three areas of open research practice (contributorship, pre-registration, and open data) and explore how and why qualitative researchers might consider engaging with these in ways that are compatible with a qualitative research paradigm. We argue it is crucial that open research practices do not (even inadvertently) exclude qualitative research, and that qualitative researchers reflect on how we can meaningfully engage with open science in psychology.     

Freely generated filters in free Boolean algebras

In this paper we will prove that ifF is a filter of a free Boolean algebra such that the minimal cardinality of the set of generators ofF is an uncountable regular cardinal or a singular cardinal with uncountable cofinality thenF is freely generated.Presented byPiotr Wojtylak
