Continuity of personality patterning from 3 to 15 years in a longitudinal sample

A longitudinal sample of 97 subjects was rated at 3, 7, 11 and 15 years on variables selected as indices of Extraversion-Introversion (EI) and Neuroticism (N) or emotionality. Principal factor analysis and Varimax rotation were performed at each age. Continuity of patterning of the variables across the four ages was determined before, and after, rotation of the items to maximal contiguity by Kaiser's method. Two principal factors, clearly identifiable as EI and N, displayed very high continuity, as did 45 rotated factors, according to Gray's model. Four Varimax factors, which initially appeared dissimilar at different ages, were shown to display high continuity, in terms of loadings on standard reference axes, after alignment of the item vectors. Thus the inadequacy of simply comparing factors as they happen to emerge, was clearly demonstrated.     

Comprehension of past and future reference revisited

Sentences containing either past tense, future tense, before, or after were presented with sets of sequential pictures to 150 children from 3 to 7 years. Analysis of errors and correct answers led to the following conclusions: (a) Linguistic factors had a major influence on the results, (b) past and future are understood first as mutually exclusive domains, (c) understanding of linguistic reference to past and future increases gradually from 3 through 7 years, and (d) the ability to temporally decenter increases with age. In addition, before and after were better understood than past or future verb tense. This finding is discussed in terms of (a) the difficulty of establishing the limits of the present in relation to past and future, (b) the center picture serving as a reference point for sentences with before and after, and (c) the difference between understanding reference to three sequenced actions and understanding reference to the sequence of past, present, and future relations.     

What do children and adolescents say they do during video game play?

We examined the problem-solving behaviors that 5th, 6th, and 7th graders used to negotiate a novel recreational video game. Students were characterized as frequent or infrequent players and instructed to think aloud during game play for 20 consecutive minutes. Comments were used to make inferences about the students' problem-solving behaviors while playing. These comments were then linked to game performance. Among all students, the greatest number of comments concerned their actions and game events at a given point in game play. Females made greater reference to strategies for game play and process goals whereas males made greater reference to their evaluations of the game and when they reached an impasse. Among 5th graders, reference to impasse and rules for game play was linked to better game performance; among 7th graders, reference to insight about how to enact a specific move or circumvent an impasse was related to better performance.     

Attentional capture by onsets and offsets

Three experiments were conducted to examine whether human infants would form a categorical representation for the spatial relation between. Experiment 1 showed that 6- and 7-month-olds familiarized with stimuli depicting a diamond in different locations between two reference bars subsequently preferred a stimulus displaying the diamond located outside the bars over a stimulus displaying the diamond located in a novel position between the bars. Experiments 2 and 3 revealed that this preference could not be attributed to a failure to discriminate the location changes of the diamond between the bars or an a priori preference. The overall pattern of results indicates that 6- and 7-month-olds had formed a categorical representation for between. The findings are discussed in terms of factors affecting development of categorical representations for spatial relation information.

A multidimensional scaling approach to mental multiplication

Adults consistently make errors in solving simple multiplication problems. These errors have been explained with reference to the interference between similar problems. In this paper, we apply multidimensional scaling (MDS) to the domain of multiplication problems, to uncover their underlying similarity structure. A tree-sorting task was used to obtain perceived dissimilarity ratings. The derived representation shows greater similarity between problems containing larger operands and suggests that tie problems (e.g., 7 x 7) hold special status. A version of the generalized context model (Nosofsky, 1986) was used to explore the derived MDS solution. The similarity of multiplication problems made an important contribution to producing a model consistent with human performance, as did the frequency with which such problems arise in textbooks, suggesting that both factors may be involved in the explanation of errors.     

Computer‐assisted reading intervention with a phonics approach for children using cochlear implants or hearing aids

The present study examined computer‐assisted reading intervention with a phonics approach for deaf and hard of hearing (DHH) children in Sweden using cochlear implants or hearing aids, or a combination of both. The study included 48 children, 5, 6 and 7 years of age. Sixteen children with normal hearing (NH) served as a reference group. The first purpose of the study was to compare NH and DHH children's reading ability at pre and post‐intervention. The second purpose was to investigate effects of the intervention. Cognitive and demographic factors were analyzed in relation to reading improvement. Results showed no statistically significant difference for reading ability at the group level, although NH children showed overall higher reading scores at both test points. Age comparisons revealed a statistically significant higher reading ability in the NH 7‐year‐olds compared to the DHH 7‐year‐olds. The intervention proved successful for word decoding accuracy, passage comprehension and as a reduction of nonword decoding errors in both NH and DHH children. Reading improvement was associated with complex working memory and phonological processing skills in NH children. Correspondent associations were observed with visual working memory and letter knowledge in the DHH children. Age was the only demographic factor that was significantly correlated with reading improvement. The results suggest that DHH children's beginning reading may be influenced by visual strategies that might explain the reading delay in the older children.     

Predicting career-entry pay expectations: The role of gender-based comparisons

This research investigated three sets of factors (career path factors, perceived job inputs, and reference group comparisons) as predictors of career-entry pay expectations for management students about to enter the workforce. As predicted, reference group comparisons accounted for a larger proportion of unique variance in students' pay expectations than either career path factors or perceived job inputs. In addition, same-sex comparisons were stronger predictors of career-entry pay expectations than opposite-sex comparisons. Practical implications and directions for future research are discussed.     

The reference frame for encoding and retention of motion depends on stimulus set size

The goal of this study was to investigate the reference frames used in perceptual encoding and storage of visual motion information. In our experiments, observers viewed multiple moving objects and reported the direction of motion of a randomly selected item. Using a vector-decomposition technique, we computed performance during smooth pursuit with respect to a spatiotopic (nonretinotopic) and to a retinotopic component and compared them with performance during fixation, which served as the baseline. For the stimulus encoding stage, which precedes memory, we found that the reference frame depends on the stimulus set size. For a single moving target, the spatiotopic reference frame had the most significant contribution with some additional contribution from the retinotopic reference frame. When the number of items increased (Set Sizes 3 to 7), the spatiotopic reference frame was able to account for the performance. Finally, when the number of items became larger than 7, the distinction between reference frames vanished. We interpret this finding as a switch to a more abstract nonmetric encoding of motion direction. We found that the retinotopic reference frame was not used in memory. Taken together with other studies, our results suggest that, whereas a retinotopic reference frame may be employed for controlling eye movements, perception and memory use primarily nonretinotopic reference frames. Furthermore, the use of nonretinotopic reference frames appears to be capacity limited. In the case of complex stimuli, the visual system may use perceptual grouping in order to simplify the complexity of stimuli or resort to a nonmetric abstract coding of motion information.     

Navigational place learning in children and young adults as assessed with a standardized locomotor search task

Spatial behaviour was investigated using a spatial learning task based on the Radial Arm Maze, the Morris Water Maze, and open‐field search‐task procedures. Ninety‐six healthy children from six age groups (3, 4, 5, 7, 10 and 12 years) with no history of CNS disorders were studied with respect to the emergence of position‐, cue‐ and place responses. Participants were to detect x out of n hidden locations, frames of reference could be varied systematically, and three spatial memory errors and speed of navigation were recorded automatically. Task difficulties were equivalent for each age group. Results showed that navigational place learning was fully developed by the age of 10, whereas participants relied on cue orientation up to age 7. Even in the youngest group, the task could be achieved without relying on egocentric orientation, provided that proximal cues were presented. Most of the errors were of the reference memory type, whereas working memory errors were extremely rare. Speed of navigation markedly improved between age 5 and 7. An additional experiment showed that navigational place‐learning behaviour was clearly dependent on distal cues. A third study showed that in young adults, learning of the spatial layout improved, but performance on the place task did not improve any further. No sex differences were observed.     

Large systematic deviations in a bimanual parallelity task: further analysis of contributing factors

Previous studies showed that what subjects haptically perceive as parallel deviates largely from what is actually physically parallel [Perception 28 (1999) 1001; Acta Psychol. 109 (2002) 25; Perception 28 (1999) 781]. It also turned out that the deviations were strongly subject-dependent. It was hypothesized that what is haptically parallel is decided in a frame of reference intermediate to an allocentric and an egocentric one. The purposes of the present study were to collect more evidence for this hypothesis and to investigate the factor(s) that determines the specific weighting between the two reference frames. We found a highly significant reversal of a haptic oblique effect (in context: larger systematic deviations for oblique orientations) for subjects with large deviations. This reversal provides convincing evidence that an intermediate frame of reference is used for the decision of haptic parallelity. Contrary to common expectation, several factors that might have been of influence on the weighting of the two frames of reference, such as arm length, arm span, shoulder width, turned out to be irrelevant. Surprisingly, the only factors that seem to be of influence are gender and job experience or education.     

Social cognitive development in resolutions of misunderstandings

Dyads of Ss from six age groups (range 7 to 22 years) were induced to misunderstand each other in each of three conditions: 1. Biased encoding in the speaker. 2. Biased decoding in the listener. J. Biases in both speaker and listener. Young Ss explained faulty behavior and attributed responsibility be reference to listeners, older Ss explained by reference to listeners and attributed responsibility to speakers. An increase of insight into listeners' bias was shown throughout the age span, whereas speakers' bias was not mentioned in Ss' explanations. The results were interpreted in terms of development of differentiation and integration of the social roles of speakers and listeners.     

The relationship of offending style to psychological and social risk factors in a sample of adolescent males

Research has indicated that life‐course persistent offenders typically vary their offending style, following a criminal career progression from co‐ to solo‐offending. Few studies have investigated the offenders who contemporaneously mix their style of offending. A sample of 1,047 male adolescent offenders from the Pathways to Desistance study was investigated over a 7‐year period. Participants were identified as solo, co or contemporaneous mixed style (CMS) offenders for each wave of data and one‐way between groups analysis of variance was conducted to examine variations between the different offending styles in terms of offending frequencies, exposure to violence, peer antisocial behaviour and influence, resistance to peer influence, impulse control and psychopathy. CMS offenders were found to consistently report significantly higher rates of offending and present significantly higher negative risk factors and lower protective risk factors than solo‐ and co‐offenders for the duration of the study. A multinomial logistic regression was used to investigate predictors of offending style with CMS as the reference category. Higher levels of exposure to violence and peer antisocial behaviour and lower levels of impulse control predicted membership of the CMS group for the first part of the study when compared with co‐offenders; and higher levels of exposure to violence and peer antisocial behaviour continued to predict CMS offending when compared to solo‐offenders until the end of the study.     

A new method for assessing squash tactics using 15 court areas for ball locations

Tactics in squash have typically been assessed using the frequency of different shot types played at different locations on the court either without reference to other relevant information or on the basis of the preceding shot. This paper presents a new squash specific method for categorizing court locations in which the ball was played, a novel techniques for assessing the reliability of this method and presents typical shots responses in these new areas controlled for preceding shot as well as the time between shots and the handedness of the players. Twelve games were viewed using the SAGIT/Squash software and 2907 shots viewed a second time from a video image taken from behind the court with an overall agreement of 88.90% for the court location data and 99.52% for shot type. 3192 shots from 9 matches from the 2003 World Team Championships were analyzed in SAGIT/Squash. In the court areas analyzed between 2 and 7 shot responses were predominant suggesting tactical patterns were evident. This was supported by differences evident between shot responses played from the two back corners where the backhand side was characterized by a predominance of straight drives whereas straight and crosscourt drives were played on the forehand side. These results tended to confirm that tactics i.e., consistent shot types, are played although these are only apparent when factors that determine shot selection are accounted for. This paper has controlled for some of these factors but others need to be considered e.g., if individual player profiles are to be ascertained.     

Factors affecting compliance with reference check requests

Structured reference checks have been demonstrated to be a reliable and valid predictor of job performance. However, the reference check is a unique assessment method for personnel selection in that a third party, the reference provider, is the source of the critical information on the candidate. If a reference provider is unwilling to either partially or fully comply with a reference check request, the usefulness of the reference check is likely to be compromised. This study examined the factors affecting compliance of the potential reference provider with a reference check request. The sample consisted of 905 U.S. adults who were recruited through the Prolific online crowdsourcing platform ( https://prolific.ac ). We asked the participants a series of questions related to their actual experiences over the past year in responding to reference check requests. We also included a between‐subjects scenario that examined whether job candidate performance, relationship to job candidate, and method of providing the employment reference would affect hypothetical compliance. The results of the study can be used to more deeply understand the factors that are related to the compliance of the reference provider, and as a result, more fully understand the value of the reference check for selection.     

不同语义水平下参照方式、情绪效价和特质评价对记忆的影响

为了探索影响记忆的深层次因素及其作用机制,采用内隐实验范式,考察了不同语义水平下参照方式、情绪效价和特质评价对记忆的影响。结果发现,参照方式、情绪效价和特质评价分别对记忆产生了显著的影响;在不同语义水平下,自我相关的特质词和非特质词的记忆优势表现在不同的再认提取阶段;个体对自我相关的消极词表现出显著的记忆优势;参照方式、情绪效价和特质评价的交互作用不显著。结果表明,参照方式、情绪效价和特质评价是对记忆产生影响的独立因素,但参照方式对记忆的影响受到情绪效价和特质评价的制约。     

A factorial study of fluency in writing

A factorial study of fluency was undertaken to test an hypothesis that at least two fluency abilities would be measured by a battery composed both of word fluency tests used by Thurstone and tests of fluency described by several British investigators. Twenty-eight tests, including ten reference tests for five primary mental abilities, were administered to 181 high-school seniors. Ten centroid factors were extracted, a simple structure was found, and eight factors were interpreted. Five factors defined were the following reference abilities: memory (M), number (N), reasoning (R), verbal comprehension (V), and perceptual speed (P), the last one being somewhat tentatively identified. The main finding is the analysis of fluency into two factors: word fluency (W) and ideational fluency (F). Word fluency is defined as a facility in producing single, isolated words that contain one or more formal restrictions, without reference to the meaning of the words. Ideational fluency is described as a facility in expressing ideas by the use of words and their meanings. Another verbal ability indicated is tentatively interpreted as verbal versatility, the ability to express essentially the same idea by means of several different words or combinations of words.The writer wishes to express his appreciation to Dr. L. L. Thurstone for his guidance throughout the study and for providing facilities and materials needed; to Miss Jessie LaSalle and the Washington, D. C., high schools for providing the subjects; to Ledyard Tucker, Frank Medland, and Mrs. Virginia Brown for computational assistance; and to others who gave aid during the study.     

Personal constructs, performance schemata, and “folk theories” of subordinate effectiveness: Explorations in an army officer sample

This research employs personal construct theory (Kelly, 1955)to explore the content of categories or schemata that may be used in making work performance judgments. Twenty-five experienced U.S. Army officers, focusing on the job of noncommissioned officer (NCO; first-line supervisor), generated independently a total of 189 personal work constructs that they believe differentiate between effective and ineffective NCOs. The officer subjects numerically defined each of their own 6–10 constructs by rating the similarity between each of these constructs and each of 49 reference performance, ability, and personal characteristics concepts. Correlations were computed between the subject-provided similarity ratings for the constructs, and the 189 × 189 matrix was factor analyzed. Six interpretable content factors were identified (e.g., Technical Proficiency, Organization), with 123 of the 189 constructs from 23 of the 25 subjects loading substantially on these factors. Findings here suggest that a core set of concepts is widely employed by these officers as personal work constructs, but that different officers emphasize different combinations of this core set. The personal constructs elicited from officer subjects are likened to performance schemata and “folk theories” of job performance.     

A new Bayesian procedure for the estimation of the referees' decision thresholds and agreement. The case of professional handball refereeing

In double refereeing, agreement between referees is fundamental for the achievement of a flawless and smooth refereeing activity. Nonetheless, the agreeement can be affected by several external and internal factors, with a negative impact on the consistency of the refereeing and the fluidity of the game. The referee’s Decision Threshold (DT) is the limit above which the evidence of a foul results in the call of an infraction by the referee. It represents the individual refereeing style, and it is one of the factors that can contribute to low agreement between the referees. We present an application of a new Bayesian procedure to estimate referee’s DT in a typical refereeing task. To this end, 56 italian professional handball (FIGH) referees were asked to evaluate 96 potential foul plays, belonging to four different infraction types: 7-m throw, passive play, offensive foul, disciplinary sanctions. The proposed method provides information about: (i) referee’s individual DT; (ii) the agreement between pairs of referees (i.e., one-to-one); (iii) the agreement between each referee and all the other referees (i.e., one-to-total); (iv) the agreement between each referee and a reference referee (i.e., one-to-expert); (v) the proportion of agreement between the referees and a reference referee for each potential foul play. Sport federations would profit by this procedure in different ways: by using the information about the DT to train referees, by detecting referees with a low agreement with their colleagues or with the reference referee, by focusing training on specific plays to improve the arbitration class internal consistency.     

A psychometric investigation of the eysenck personality questionnaire (revised) and its relationship to the I.7 impulsiveness questionnaire

The present study investigated the psychometric properties of the Eysenck Personality Questionnaire-Revised (EPQ-R) and the I.7 Impulsiveness Questionnaire. 307 Ss (215 female, 92 male) completed the EPQ-R and the I.7. Scale means and the standard deviations were calculated, scale reliability tested, scale scores intercorrelated and the resulting matrices were factor-analysed. The items from the EPQ-R and the I.7 were submitted to an item factor analysis. The results of the present study were quite similar to those reported by Eysenck, Eysenck and Barrett (1985) for the EPO-R and those reported by Eysenck, Pearson, Easting and Allsopp (1985) for the I.7. It was concluded that the EPQ-R represents an improvement on the 90-item EPQ and that the I.7 represents an adequate and reliable measure of Impulsiveness, Venturesomeness and Empathy. The relationships between the EPQ-R factors and the I.7 factors are also discussed.
