Developmental models for children's temperament: alternatives to chronometric polynomial curves

Partridge and Lerner (2007), in a secondary analysis of the New York Longitudinal Study, employed a chronometric polynomial growth curve model to argue that the developmental course of difficult temperament follows a non‐linear trajectory over the first 5 years of life. The free curve slope intercept (FCSI) growth curve model of Meredith and Tisak (1990) is presented as a preferable conceptual alternative because it contains a number of currently popular statistical models, including repeated measures multivariate analysis of variance, factor mean, linear growth, linear factor analysis, and hierarchical linear models as special cases. As such, researchers can compare the fit of each of these models relative to the FCSI model, and, at times, to each other. The present paper conducts a re‐analysis of the data, and establishes that fit of the FCSI model is arguably better than other statistical alternatives. The FCSI model is also used as the basis for identifying subgroups of individuals with their qualitatively distinct growth patterns within a growth mixture modeling framework.

记叙文阅读中人物第一印象的即时更新

采用移动窗口技术探讨读者在记叙文阅读中是否对人物第一印象进行即时更新。实验1探讨读者在阅读过程中是否会根据第一印象建构人物特征情境模型。实验2探讨已经形成的人物特征情境模型是否会受最近印象的影响得以更新。实验3探讨在明确描述人物特征的情况下,读者是否仍然会更新人物特征情境模型。研究结果表明,记叙文阅读中,读者会对人物第一印象进行即时更新,表现出首因效应向近因效应的转化。     

The structure of the State Hope Scale

The present research aimed to examine the factorial structure of the State Hope Scale (SHS). In Study 1, using confirmatory factorial analyses, two factorial structures were contrasted: a single-factor mode (representing a general hope construct) and a second-order factor model (with general hope characterized by agency and pathways). Results revealed that the two-factor model was more likely to be replicated. Furthermore, invariance analyses revealed that the two-factor structure applied equally across age groups and gender. In Study 2, the factorial structure of the SHS was evaluated again. Once more, results confirmed the superiority of the two-factor model. In addition, hope was positively linked to mental health.     

Non-reciprocal responsibilities and the banquet of the kingdom

Granted the far-flung impacts of humanity on the future and the biosphere, Hans Jonas has rightly called for our responsibilities to be reconceptualised, and where responsibilities are non-reciprocal Chris Groves has put forward a model of the ethics of care to underpin them. In view, however, of Derek Parfit's work on responsibilities with regard to the possible but unidentifiable people of alternative possible futures, the author suggests that an ethical model grounded in relations, while helpful, is insufficient with regard to these impersonal responsibilities, and is not sufficiently strengthened by resorting to ‘constitutive value’. To meet the need for further models, he first presents two familiar ones (those of bequests or legacies and of stewardship or trusteeship), and then a new model appropriate for responsibilities towards unidentifiable parties, based on hospitality and generosity, and Jesus' parable of the great banquet as in Luke 14. This model also has its shortcomings, but could, alongside the others, assist people to take non-reciprocal responsibilities seriously.     

Performed or observed keyboard actions affect pianists' judgements of relative pitch

Action can affect visual perception if the action's expected sensory effects resemble a concurrent unstable or deviant event. To determine whether action can also change auditory perception, participants were required to play pairs of octave-ambiguous tones by pressing successive keys on a piano or computer keyboard and to judge whether each pitch interval was rising or falling. Both pianists and nonpianist musicians gave significantly more “rising” responses when the order of key presses was left-to-right than when it was right-to-left, in accord with the pitch mapping of the piano. However, the effect was much larger in pianists. Pianists showed a similarly large effect when they passively observed the experimenter pressing keys on a piano keyboard, as long as the keyboard faced the participant. The results suggest that acquired action–effect associations can affect auditory perceptual judgement.     

Further attempts to clarify the importance of category variability for categorisation

The issue of how category variability affects classification of novel instances is an important one for assessing theories of categorisation, yet previous research cannot provide a compelling conclusion. In five experiments we reexamine some of the factors thought to affect participant performance. In Experiments 1 and 2, participants almost always classified the test item as belonging to the high variability category. By contrast, in Experiment 3 we employed an alternative experimental paradigm, where the difference in variability of the two categories was less salient. In that case, participants tended to classify a test item as belonging to the low variability category. Two additional experiments (4 and 5) explored in detail the differences between Experiments 1, 2 on the one hand, and 3 on the other. Some insight into the underlying psychological processes can be provided by computational models of categorisation, and we focus on the continuous version of Anderson's (1991) Rational Model, which has not been explored before in this context. The model predicts that test instances exactly halfway between the prototypes of two categories should be classified into the more variable category, consistent with the bulk of empirical findings. We also provided a comparison with a slightly reduced version of the Generalised Context Model (GCM) to show that its predictions are consistent with those from the Rational Model, for our stimulus sets.     

“I see what you mean”: Oral deaf individuals benefit from speaker's gesturing

Recent studies in the psychological literature reveal that cospeech gestures facilitate the construction of an articulated mental model of an oral discourse by hearing individuals. In particular, they facilitate correct recollections and discourse-based inferences at the expense of memory for discourse verbatim. Do gestures accompanying an oral discourse facilitate the construction of a discourse model also by oral deaf individuals trained to lip-read? The atypical cognitive functioning of oral deaf individuals leads to this prediction. Experiments 1 and 2, each conducted on 16 oral deaf individuals, used a recollection task and confirmed the prediction. Experiment 3, conducted on 36 oral deaf individuals, confirmed the prediction using a recognition task.     

Phonological abstraction in the mental lexicon

A perceptual learning experiment provides evidence that the mental lexicon cannot consist solely of detailed acoustic traces of recognition episodes. In a training lexical decision phase, listeners heard an ambiguous [f–s] fricative sound, replacing either [f] or [s] in words. In a test phase, listeners then made lexical decisions to visual targets following auditory primes. Critical materials were minimal pairs that could be a word with either [f] or [s] (cf. English knife–nice), none of which had been heard in training. Listeners interpreted the minimal pair words differently in the second phase according to the training received in the first phase. Therefore, lexically mediated retuning of phoneme perception not only influences categorical decisions about fricatives (Norris, McQueen, & Cutler, 2003), but also benefits recognition of words outside the training set. The observed generalization across words suggests that this retuning occurs prelexically. Therefore, lexical processing involves sublexical phonological abstraction, not only accumulation of acoustic episodes.     

Developing new treatments: on the interplay between theories, experimental science and clinical innovation

It is often argued that behaviour therapy and cognitive-behaviour therapy have a sound theoretical and experimental basis. In the early days of behaviour therapy, the learning theory accounts that were the basis of treatment made clear suggestions about the procedures that were likely to be effective in treatment. In contrast, more recent cognitive-behavioural models tend to specify targets for therapy, but not the procedures that might be optimal for changing the targets. As a consequence, a considerable amount of work has to be done in order to create an effective cognitive-behavioural treatment from a promising cognitive-behavioural model. The process by which cognitive-behavioural treatments are developed is rarely discussed in the literature. For this reason, the way in which one group has used a mixture of phenomenological, experimental and treatment development studies to create effective cognitive therapy programmes for anxiety disorders is described.
