The processing of English regular inflections: Phonological cues to morphological structure

Previous studies suggest that different neural and functional mechanisms are involved in the analysis of irregular (caught) and regular (filled) past tense forms in English. In particular, the comprehension and production of regular forms is argued to require processes of morpho-phonological assembly and disassembly, analysing these forms into a stem plus an inflectional affix (e.g., {fill}+{-ed}), as opposed to irregular forms, which do not have an overt stem+affix structure and must be analysed as full forms [Marslen-Wilson, W. D., & Tyler, L. K. (1997). Dissociating types of mental computation. Nature, 387, 592-594; Marslen-Wilson, W. D., & Tyler, L. K. (1998). Rules, representations, and the English past tense. Trends in Cognitive Science, 2, 428-435]. On this account, any incoming string that shows the critical diagnostic properties of an inflected form - a final coronal consonant (/t/, /d/, /s/, /z/) that agrees in voicing with the preceding segment as in filled, mild, or nilled - will automatically trigger an attempt at segmentation. We report an auditory speeded judgment experiment which explored the contribution of these critical morpho-phonological properties (labelled as the English inflectional rhyme pattern) to the processing of English regular inflections. The results show that any stimulus that can be interpreted as ending in a regular inflection, whether it is a real inflection (filled-fill), a pseudo-inflection (mild-mile) or a phonologically matched nonword (nilled-nill), is responded to more slowly than an unambiguously monomorphemic stimulus pair (e.g., belt-bell). This morpho-phonological effect was independent of phonological effects of voicing and syllabicity. The findings are interpreted as evidence for a basic morpho-phonological parsing process that applies to all items with the criterial phonological properties.     

Rating Level and Accuracy as a Function of Rater Personality

We investigated the predictability of rating level and two measures of rating accuracy from rater Agreeableness (A) and Conscientiousness (C) scores of the Five Factor Model. One hundred and twenty‐six students made peer ratings after participating in several group exercises under conditions designed to emulate the modal peer rating system in which raters had low accountability for their ratings. Scores were correlated with average rating level (r=.18, p<.05) and both measures of rating accuracy (p<.05) and C scores were correlated with rating level (?.20, p<.05) and both measures of rating accuracy (p<.05). As suggested by Bernardin, Villanova, and Cooke (Journal of Applied Psychology, 85, 232–236, 2000), raters who were both more agreeable and less conscientious made the most lenient and least accurate ratings. Contrary to Yun, Donahue, Dudley, and McFarland (International Journal of Selection and Assessment, 13, 97–107, 2005), more agreeable raters also tended to rate the least effective performers more leniently than did other raters.     

Development of Phonological Constancy: Toddlers' Perception of Native- and Jamaican-Accented Words

ABSTRACT— Efficient word recognition depends on detecting critical phonetic differences among similar-sounding words, or sensitivity to phonological distinctiveness , an ability evident at 19 months of age but unreliable at 14 to 15 months of age. However, little is known about phonological constancy , the equally crucial ability to recognize a word's identity across natural phonetic variations, such as those in cross-dialect pronunciation differences. We show that 15- and 19-month-old children recognize familiar words spoken in their native dialect, but that only the older children recognize familiar words in a dissimilar nonnative dialect, providing evidence for emergence of phonological constancy by 19 months. These results are compatible with a perceptual-attunement account of developmental change in early word recognition, but not with statistical-learning or phonological accounts. Thus, the complementary skills of phonological constancy and distinctiveness both appear at around 19 months of age, together providing the child with a fundamental insight that permits rapid vocabulary growth and later reading acquisition.     

Procedural justice,identity and deference to the law: What shapes rule‐following in a period of transition?

The group engagement model has two core arguments. The first is that procedural justice shapes rule‐following in groups, organisations and societies. The second is that the influence of procedural justice upon rule‐following is mediated by changes in people's identification with groups. This study uses a sample of South Africans to test both arguments. While the procedural justice argument has already been widely tested and supported, this study extends that test to a society in rapid transition and upheaval. Further, it tests the identity mediation argument in the same context. The results support both arguments. Procedural justice shapes rule‐following and that influence is mediated by identification with superordinate authority.     

Explanatory Exclusion and Causal Exclusion

Given Kim’s principle of explanatory exclusion (EE), it follows that in addition to the problem of mental causation, dualism faces a problem of mental explanation. However, the plausibility of EE rests upon the acceptance of a further principle concerning the individuation of explanation (EI). The two methods of defending EI—either by combining an internal account of the individuation of explanation with a semantical account of properties or by accepting an external account of the individuation of explanation—are both metaphysically implausible. This is not, however, to reject the problem of mental explanation, for EE can be replaced with a far weaker principle, which does not require the acceptance of EI, but which generates a similar problem for dualism.

Why do Alzheimer patients have difficulty with pronouns? Working memory, semantics, and reference in comprehension and production in Alzheimer's disease

Three experiments investigated the extent to which semantic and working-memory deficits contribute to Alzheimer patients' impairments in producing and comprehending referring expressions. In Experiment 1, the spontaneous speech of 11 patients with Alzheimer's disease (AD) contained a greater ratio of pronouns to full noun phrases than did the spontaneous speech produced by 9 healthy controls. Experiments 2 and 3 used a cross-modal naming methodology to compare reference comprehension in another group of 10 patients and 10 age-matched controls. In Experiment 2, patients were less sensitive than healthy controls to the grammatical information necessary for processing pronouns. In Experiment 3, patients were better able to remember referent information in short paragraphs when reference was maintained with full noun phrases rather than pronouns, but healthy controls showed the reverse pattern. Performance in all three experiments was linked to working memory performance but not to word finding difficulty. We discuss these findings in terms of a theory of reference processing, the Informational Load Hypothesis, which views referential impairments in AD as the consequence of normal discourse processing in the context of a working memory impairment.     

The Influence of Decision Makers' Goals on Their Concerns About Procedural Justice1

Two studies examine how decision makers' goals of enhancing organizational effectiveness and promoting positive interpersonal relations shape their decision making when they are allocating scarce resources among group members. Past research has conceptualized this problem as one of balancing between the use of two distributive justice principles: equity and equality. The studies reported examine the degree to which authorities are also concerned about issues of procedural justice. The results suggest that experienced decision makers—both managerial and administrative—believe that when trying to maintain positive interpersonal relations it is as important to use decision-making procedures that will be regarded as fair (procedural justice) as it is to allocate outcomes in ways which will be regarded as fair (distributive justice). Decision makers' definitions of procedural justice are also examined.     

Aging and attitude change.

Social psychologists have proposed a variety of different models to account for people's relative openness to attitude change through the life cycle. Two of the most important models are the impressionable years model, which suggests an especially great openness to change among the young, and the lifelong openness model, which suggests that age is unrelated to openness to attitude change. Two studies were conducted to examine the openness of people of varying ages to attitude change. In both studies, the influence of personal experiences with government agencies on attitudes toward government was examined. The attitudes of older people changed as much or more in response to their personal experiences as did those of younger people. These results support the lifelong openness model of attitude change.
