Sequential or parallel decomposed processing of two-digit numbers? Evidence from eye-tracking

While reaction time data have shown that decomposed processing of two-digit numbers occurs, there is little evidence about how decomposed processing functions. Poltrock and Schwartz (1984) argued that multi-digit numbers are compared in a sequential digit-by-digit fashion starting at the leftmost digit pair. In contrast, Nuerk and Willmes (2005) favoured parallel processing of the digits constituting a number. These models (i.e., sequential decomposition, parallel decomposition) make different predictions regarding the fixation pattern in a two-digit number magnitude comparison task and can therefore be differentiated by eye fixation data. We tested these models by evaluating participants' eye fixation behaviour while selecting the larger of two numbers. The stimulus set consisted of within-decade comparisons (e.g., 53_57) and between-decade comparisons (e.g., 42_57). The between-decade comparisons were further divided into compatible and incompatible trials (cf. Nuerk, Weger, & Willmes, 2001) and trials with different decade and unit distances. The observed fixation pattern implies that the comparison of two-digit numbers is not executed by sequentially comparing decade and unit digits as proposed by Poltrock and Schwartz (1984) but rather in a decomposed but parallel fashion. Moreover, the present fixation data provide first evidence that digit processing in multi-digit numbers is not a pure bottom-up effect, but is also influenced by top-down factors. Finally, implications for multi-digit number processing beyond the range of two-digit numbers are discussed.

Mentally ill or mentally handicapped? A longitudinal study of severe learning disorder

SUMMARY

In the course of some eighteen months of psychoanalytic psychotherapy, a young woman of twenty-seven once deemed braindamaged at the age of seven years, has shown herself capable of sustaining once weekly psychotherapy. Against all expectations she has taken responsibility for her own attendance, travelling by public transport alone to her sessions. She has also taken initiatives in relation to finding work for herself.

Psychotherapy has disclosed a significant component of autism in the personality which is resorted to regularly and which seems to drag the patient into a passive acceptance of half-life which she tries not to mind. In the course of her sessions the patient has come to take more notice of her predicament and to mind more about the dissatisfactions which she experiences.

The case presented here is considered to have the characteristics of a particular group of adolescents. These are often described as “just slow” and are brought for psychiatric or psychological attention by desperate parents urgently concerned about the working future of their children.

These are individuals of whom the original definition of mental handicap contained in the Mental Health Act 1913 “a state of arrested or incomplete development of mind” would seem to offer as honest, appropriate and meaningful an assessment as the formal I.Q. score introduced in 1959. Unlike the latter, it is an assessment based on a concept of mental development. Assessment by I.Q. score has led to emphasis on training to compensate for the supposed loss of functioning and also to notions like “training for development” and “education from birth”.

In the case described here it was the abandonment of training aims and approaches which produced a dramatic improvement in the well-being of the patient and her family. Treatment is now fostering the potential in this woman to bring her own mind into action and to support in her, her own wish for personal development.     

Cognitive–motivational antecedents of career decision-making processes in Portuguese high school students: A longitudinal study

In this study we propose an integrated framework of the antecedents of identity development and well/ill-being for high school students (N = 462) in the transition to higher education/job market. One study was conducted to investigate the effects of basic psychological need-satisfaction/frustration (as proposed within self-determination theory) and career decision-making self-efficacy (posited by social cognitive career theory) on the identity dimensions and experienced well/ill-being. Three longitudinal nested models were tested: a need-satisfaction/self-efficacy main effects model, an identity main effects model and a reciprocal main-effects model. The reciprocal effects between the variables were favored by the data. Basic need-satisfaction and career decision making self-efficacy positively predicted proactive exploration and commitment-making, while basic need-frustration predicted both diminished well-being and ill-being. Reciprocally, proactive exploration investments positively predicted whereas ruminative exploration negatively predicted, need-satisfaction and career decision-making self-efficacy. Implications for the design of career interventions are discussed and suggestions for future research proposed.     

Careful calculation or a leap of faith? A field study of the translation of CBCA ratings to final credibility judgements

This field experiment investigated the influence of Criteria‐Based Content Analysis (CBCA) ratings on ultimate decision accuracy regarding the credibility of children's statements of sexual abuse. Following a selection procedure, based on case facts independent of statement quality, 21 truthful accounts and 10 fabricated accounts of 6‐ to 17‐year olds were analysed. Two experts rated the presence of the CBCA criteria and made overall credibility judgements for each statement. Rater one achieved an overall hit rate of 84% (95% for truthful statements and 60% for fabricated statements) and rater two a hit rate of 81% (81% for both truthful and fabricated statements) but the raters did not always agree. The CBCA criteria appeared more often in the truthful statements compared to the fabricated statements. Additional factors that influenced raters' credibility judgements, besides CBCA scores, are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

What predicts adjustment among law students? A longitudinal panel study

Although at the time of this article's publication, many anecdotes and cross-sectional studies had reported that law students experience significant distress during their 1st year, few researchers had controlled for prelaw school status (e.g., M. Garrison, B. Tomko, & I. Yip, 1996; L. Guinier, M. Fine, J. Balin, A. Bartow, & D. L. Stachel, 1994), and only a single group of researchers had explored a psychosocial factor that predicted these changes. The present authors tested 3 sets of potential predictors of adjustment: sources of stress, coping strategies, and relationship factors. The present data replicated declines in students' psychological health, physical health, and attitudes toward law over the 1st year of school. That result supports the generalizability and currency of previous studies. In contrast to other researchers, the present authors found few gender differences. Less relationship happiness, less emotional support, and use of less active coping tactics at the beginning of the year predicted poorer outcomes at the end of the year. Strain from academic pressures, lack of personal time, and social isolation were correlated with poorer outcomes.     

Why are some people more knowledgeable than others? A longitudinal study of knowledge acquisition

The purpose of this study was to investigate correlates of knowledge acquisition within a real-world domain-basketball. The study employed a longitudinal design and involved two sessions, with approximately 2.5 months between sessions. Session 1 occurred near the beginning of the men's college basketball season, and Session 2 occurred after the season. There was an indirect effect of interest in basketball on new basketball knowledge, via exposure to domain-relevant information. In addition, prior basketball knowledge had a strong effect on new basketball knowledge distinct from an influence through basketball exposure. This finding suggests that prior knowledge may provide a framework into which new knowledge can be integrated. By contrast, there was no effect of fluid intelligence on new basketball knowledge. Although somewhat surprising given evidence that this aspect of intelligence may play a role in the acquisition of certain types of knowledge, this finding accords with the view that knowledge is a major determinant of various aspects of cognitive functioning, including learning.     

What predicts first date success? A longitudinal study of modality switching in online dating

This study uses a longitudinal design to investigate the effects of online dating sites on first date success. Participants were surveyed before their first date with someone from an online dating site (N = 186) and again after meeting their partner in person (N = 94). As part of the survey, they also supplied the e‐mails they had sent to their partner through the dating site so their actual communication could be examined. Findings indicated that first date success was predictable from features of participants' online impressions and relational dynamics. The results are discussed in terms of their theoretical and methodological contributions to the literature on relationship development, as well as their practical implications for online dating sites and users.     

Cybertherapy or psychobabble? A mixed methods study of online emotional support

ABSTRACT

The provision of online counselling and emotional support is a subject of intense debate among service providers. The subject is explored here by triangulating data from a statistical analysis of data from a children's helpline, interviews with practitioners and a focus group. Despite practitioners' concerns relating to misinterpretation, misrepresentation and the lack of non-verbal cues, online conversations are shown to span a greater variety of topics and focus on more sensitive issues than verbal sessions. Online services have potential for reaching clients in accessible and meaningful ways. However, practitioners need to consider online-specific issues, undertake specialised training and become comfortable with these new communication formats.     

A longitudinal study of “we-talk” as a predictor of marital satisfaction

We-talk, the use of first-person plural pronouns over the use of singular pronouns when describing relationship events, is regarded as a linguistic indicator of marital relationship functioning. A meta-analysis revealed that we-talk is positively associated with relationship satisfaction. However, this literature is based mostly on cross-sectional studies. This study tested the hypothesis that we-talk would be associated with greater marital satisfaction over time. The sample comprised 77 couples enrolled in a longitudinal study of parents of preschool-aged children. We-talk was assessed at baseline during a marital discussion task about parenting challenges. Couples completed a measure of marital satisfaction at baseline, 6- and 12-month follow-ups. An actor–partner interdependence model examined the effects of spouses' we-talk on their own marital satisfaction (actor effects), and their partners' marital satisfaction (partner effects). Results indicated a positive partner effect of we-talk at baseline, but not over time. Moreover, there was an actor effect of we-talk on changes in marital satisfaction over time, whereby low actor we-talk was associated with a reduction in marital satisfaction, but high actor we-talk was not associated with such a decrease. These findings suggest that greater cognitive interdependence, as indicated by we-talk, may protect from declines in marital satisfaction over time.     

Cognitive processes in unconscious patients? A brain mapping study of the P300 potential

P300 is the most investigated component of the event-related potentials. Being the correlate of an active target discrimination and decision making process it is seen as related to cognition. Such elementary cognitive processes--as expressed in P300--can happen even in states of coma. In four of 35 comatose patients with diffuse head injury we were able to measure the P3-wave showing frontal and parietal components. Accordingly some unawakable patients can still recognize differences in pitch. The structure of components and their psychophysiological meaning are discussed.     

Which emotional regulatory strategy makes Chinese adolescents happier? A longitudinal study

Growing interest in emotion regulation is reflected in the studies of cognitive and social development. However, the extant studies mainly highlight how emotion regulation develops based on a western value system. This study utilised a longitudinal design to examine the development of emotion regulation and explored the contributions of different regulatory strategies to emotion experience regarding the early adolescent development period in a Chinese population. A total of 303 Chinese adolescents (age range = 10–14 years) were followed up in a three‐phase longitudinal study for 3 years. In each phase of the study, participants completed Adolescents Emotion Regulation Questionnaire and Daily Emotion Scale. Results of hierarchical linear regressions revealed that Chinese adolescents reported more down‐regulation. Down‐regulation is more effective than up‐regulation in enhancing desirable emotion experience and reducing undesirable emotion experience during adolescents' development. Also, the adaptive functions of emotional regulatory strategies in Chinese background were discussed.     

Is there a psychopathic element in adolescent drinking? A longitudinal study

While previous studies have examined the relationship between psychopathic traits and alcohol use in adolescents, limited empirical investigations of the longitudinal bidirectional effects of psychopathic traits and alcohol use have been conducted for this age-group. The purpose of the present study was to examine the longitudinal associations among adolescent’s psychopathic traits and their alcohol use, in order to illustrate the directional causal relationship between the two constructs, taking into account demographic effects. Participants were 334 adolescents from Cyprus. The participants responded to self-report questionnaires in two consecutive measurements within a six-month interval. Data were analyzed with cross-lagged structural equation modelling. Results indicated that the Dependence alcohol symptoms in Time 1 were significant predictors of the Interpersonal dimension of psychopathy in T2, and the Behavioural dimension of psychopathy in T1 was a significant predictor of Dependence alcohol symptoms in T2, regardless of previous levels of psychopathy and alcohol use, gender and age effects. Implications for research are discussed.     

Do health beliefs about COVID-19 predict morbidity? A longitudinal study

In a highly powered (N ≈ 5000), six-months longitudinal study (December 2020-May 2021), we tested the assumption that beliefs concerning COVID-19 and the precautions against it predicted morbidity. Six months after having filled out a survey measuring beliefs about the disease and the precautions against it, participants reported if they were or had been ill with COVID-19. A lower likelihood of being or having been ill with COVID-19 was predicted by personal optimism concerning infection, perceived personal control over infection, perceived effectiveness of precautions, and self-reported personal or better-than-average adherence to the precautions. A higher likelihood of being or having been ill with COVID-19 was predicted by perceived personal control over a good outcome of an infection, egocentric impact perception concerning the impact of the disease, perceived difficulty of adherence to the precautions, and both personal and egocentric impact perception concerning the impact of the precautions. Comparative optimism did not predict morbidity, nor did personal optimism concerning severe disease or a good outcome, perceived personal control over severe disease, and moralization of the precautions. We discuss implications for public health communication.     

Are facilitated mentoring programs beneficial? A randomized experimental field study

Results from a pretest–posttest randomized field experiment study with a control group comparing the impact of high- and low-level-facilitated mentoring programs on new employees’ performance and perceptions about their jobs and organization were reported in this paper. Results indicated increases in job satisfaction, organizational commitment, person-organization fit and performance by participants in both mentoring programs with larger gains made by the high-level-facilitated group. These results suggest that a formal mentoring program can have positive effects on employee’s work-related attitudes, cognition and behavior with significantly greater gains made by formal mentoring programs with higher levels of facilitation.     

Excitement or anxiety? A case study of Indian postgraduate sojourners at University of Nottingham

Moving to a new country is often seen as a disturbing event in sojourners' lives. Several models of adjustment postulate that the first phase of the sojourn is either categorised by euphoria or anxiety. Using a case study of three Indian Postgraduate students, this paper investigates whether the beginning phase of these sojourners was euphoric or anxious in nature. The findings revealed that they had varied experiences and even mixed experiences that were both pleasant and/or unpleasant which were in turn determined by their individual differences and personal experiences. Another salient finding of this study was that the psychological side of the sojourn starts much before the students have even first set foot in the UK. This could serve as a basis for further research and to conceptualise a model of cultural adjustment that takes into account the impact of the pre-arrival phase on the overall sojourn experience.     

Retinal projection or size constancy as determinants of the horizontal-vertical illusion?

To compare the influence of the projected retinal size and of the figure size on the perception of the horizontal-vertical illusion, the target size, the viewing distance, and the slant of an illusion figure were varied. In the first experiment the illusion produced by two figures of the same object size but of different retinal size was compared with that of two figures projecting the same retinal size but differing in object size. The illusion diminished when the size of the retinal projection was increased, whereas a change in figure size did not change the illusion. In Exp. II the illusion figure was tilted backwards which reduced the retinal projection of the 'vertical' figure limb. The illusion decreased and became negative as a function of the retinal projection, but this decrease was relatively small compared with the reduction of the retinal image. The results are interpreted as supporting a retinal origin as an explanation of the illusion. Although there is strong evidence for size-constancy scaling in a tilted figure, constancy scaling is considered of minor importance as a determinant of the usual illusion.     

How are employees at different levels affected by privatization? A longitudinal study of two Swedish hospitals

Despite the amount of privatizations around the world in recent decades, only limited research attention has been paid to how privatization affects the employees. The effects are likely to vary depending on the individual's position in the organization. The aim of this study was to investigate how employees' work‐related attitudes and strain changed after privatization of a Swedish acute care hospital, and to analyze whether the effects of privatization differed between employees at various hierarchic levels. Questionnaire data collected at a hospital 1 year before and 2 years after privatization, as well as at a hospital which remained a public administration unit, suggest only limited effects of privatization on a general level, but that employees at various hierarchic levels may be affected differently. While employees at a high level (physicians) and low level (assistant nurses) reported only marginal differences over time in work attitudes and strain, also in comparison with their colleagues at the comparison hospital, work attitudes of employees at the intermediate level (registered nurses) decreased after privatization. These results emphasize the importance of taking hierarchic level into account when a privatization is implemented and analyzed.     

Do early lexical skills predict language outcome at 3 years? A longitudinal study of French-speaking children

Early language development is considered critical for children’s adjustment in school, for social adaptation and for later educational achievement. Despite the role of children’s receptive skills as a foundation for later productive word use, receptive language skills have received surprisingly little attention. The present research extends recent work on the prediction of preschool language skills by exploring whether a decontextualized measure of lexical comprehension can account for unique variance in preschool language skills above and beyond parent report and how early such a prediction can be made. For this purpose, 65 French-speaking children have been tested at 16, 22, 29 and 36 months.The results of the current study suggest that up to the age of two, although parent reports of lexical comprehension and/or production account for a portion of variance in later receptive, productive or general language outcome, they have less predictive validity than a direct measure of early lexical comprehension. By contrast, after age two, parent reported vocabulary production is the strongest predictor of later language production skills.
