The functional theory of human values: From intentional overlook to first acknowledgement—A reply to Schwartz (2014)

Schwartz has been aware of the Functional Theory of Values for over a decade. For the first time, Schwartz (2014) acknowledges the Gouveia theory and provides considerations based on the Gouveia, Milfont, and Guerra (2014) study. In this reply we present a historical overview of the development of the theory, noting unwarranted barriers to the publication of our work. We then address his comments, focusing on the theoretical innovations of the theory and remarking that recent refinements of Schwartz’s model were already evident in the Gouveia theory. Hypotheses tested in Gouveia et al. (2014) are also re-tested and supported with European Social Survey data using the Schwartz PVQ-21. We conclude by summarizing current projects that offer further opportunities to continue the theoretical debate.     

A Test of the Adams-Creamer Decay Hypothesis for the Timing of Motor Responses

The Adams-Creamer hypothesis states that S uses the decay of proprioceptive feedback from an early portion of a movement to cue a timed response at some later time. This hypothesis was tested by creating passive left-arm movement in one group and withholding it from another, and having Ss make a right-hand response when exactly 2.0 sec. had elapsed since the end of the movement Ss with left-arm feedback had less absolute and algebraic error, and greater within-S consistency than did the no-movement control Ss and, when KR was withdrawn, Ss with left-arm movement regressed less than did Ss without the left-arm movement, which provided 2 lines of support for the decay hypothesis.     

Impact de la motivation autodéterminée et de l’engagement affectif sur l’intention de rester : une étude chez les militaires

Conducted within the Canadian Forces (N=652), this study explores the role of self-determined motivation and affective commitment in relation to personnel retention within the military. Three groupings of variables are used in order to shed light on the mechanisms underlying personnel retention: a) distal antecedents (i.e. leadership styles), b) proximal antecedents (i.e. group cohesion and work climate) and c) mediators (i.e. self-determined motivation and affective commitment). Illustrated through a structural model, results demonstrate the existence of a partial mediator effect from affective commitment in the relationship between self-determined motivation and intention to stay. These findings are discussed in regards of their implications from theoretical and practical perspectives.     

School enrolment and executive functioning: A longitudinal perspective on developmental changes,the influence of learning context,and the prediction of pre-academic skills

The present two-year longitudinal study addressed developmental changes in different aspects of executive functioning (i.e., inhibition, updating, and cognitive flexibility) in a sample of 264 children aged between 5 and 7 years. Of special interest were issues of developmental progression over time, the influence of learning context and the predictive power of executive functions and school context for emerging academic skills. The results revealed pronounced improvements in all executive measures, both over time and as a function of age. For the learning context, small and age-dependent effects on executive skills were found. Inhibition uniquely contributed to the prediction of aspects of emerging academic skills, over and above chronological age and language skills.     

Impaired task switching performance in children with dyslexia but not in children with autism

Problems with cognitive control in both autism and dyslexia have already been reported in different studies. The present study specifically examined task-switching performance in children with autism and dyslexia. For this purpose, a multiple-trial paradigm was used with cues for colour- and shape-matching tasks presented before a run of trials. The cue could imply a task switch (when the cue changed the task) or a task repetition (when the cue did not change the task). Both reaction times and error rates were measured for switching, restarting, and general task performance. Participants were children with autism (24) and with dyslexia (25) and healthy controls (27) with normal IQ and ages from 12 to 18 years. The main finding was that while similar switching performance was observed between children with autism and the healthy controls, children with dyslexia showed a significant switch-specific delay relative to both healthy controls and children with autism. Furthermore, no deficit in restarting performance was observed for any of the two patient groups. Finally, additional evidence is provided for a more general deficit in information processing in dyslexia. Our data suggest that children with autism are able to switch between tasks in a similar way as do normally developing children as long as the tasks are unambiguously specified. Furthermore, the data imply switch-specific deficits in dyslexia additionally to the deficits in general information processing already reported in the literature. The implications of our data are further discussed in relation to the interpretation of the Wisconsin Card Sorting Test.     

Understanding the role of executive control in the Implicit Association Test: Why flexible people have small IAT effects

The goal of the present research was to investigate the role of three central-executive functions—switching of mental sets, inhibition of prepotent responses, and simultaneous storage and processing (i.e., working-memory capacity)—in accounting for method variance in the Implicit Association Test (IAT). In two studies, several IATs with unrelated contents were administered along with a battery of central-executive tasks, with multiple tasks tapping each of the above executive functions. Method variance was found to be related to the switching factor, but not to the inhibition factor. There was also evidence for a small independent contribution of the working-memory capacity factor. The findings constrain process accounts of the IAT, lending support to an account in terms of task-set switching, and they have consequences for applications.     

Helping Children Access and Use Services: A Review

High rates of dropping out from mental health services are documented for children and their families. These high rates exist at different treatment stages, in different service settings, and for different populations of children and families. Some researchers have developed and tested engagement interventions to address barriers to service access and use and increase participation in services by children and their families. Studies of engagement interventions for children and their families are critically reviewed in this paper. Overall, the engagement interventions were effective in increasing attendance at first appointments. Only those with an ecological and total service delivery approach reduced the drop-out rate. However, even then, the drop-out rate was 26% to 29%. Suggestions for future research are made, including ascertaining from children and families their reasons for quitting or staying in treatment, comparing the outcomes of drop-outs with the outcomes of those who remain in treatment, developing and testing conceptual models of engagement for subgroups of at-risk children and their families, and examining the cost-effectiveness of engagement interventions.     

意向保持间隔对时间性前瞻记忆的影响

通过两个实验来探讨意向保持间隔对时间性前瞻记忆的影响。实验一仅通过嵌入前瞻目标的背景任务来操纵保持间隔,实验二通过在背景任务之前加入不同时长的填充任务来改变意向保持间隔。结果发现,(1)背景任务中的保持间隔越长,前瞻记忆成绩越差;(2)背景任务中的保持间隔和填充任务的时长对前瞻记忆的影响存在交互作用。成绩最好的为15min-2min组,最差的为15min-15min组。结果表明,背景任务和填充任务阶段对于个体保持前瞻意向可能有不同的功能。     

Efficient nonparametric approaches for estimating the operating characteristics of discrete item responses

Rationale and the actual procedures of two nonparametric approaches, called Bivariate P.D.F. Approach and Conditional P.D.F. Approach, for estimating the operating characteristic of a discrete item response, or the conditional probability, given latent trait, that the examinee's response be that specific response, are introduced and discussed. These methods are featured by the facts that: (a) estimation is made without assuming any mathematical forms, and (b) it is based upon a relatively small sample of several hundred to a few thousand examinees.Some examples of the results obtained by the Simple Sum Procedure and the Differential Weight Procedure of the Conditional P.D.F. Approach are given, using simulated data. The usefulness of these nonparametric methods is also discussed.This research was mostly supported by the Office of Naval Research (N00014-77-C-0360, N00014-81-C-0569, N00014-87-K-0320, N00014-90-J-1456).
