The ghost of Christmas future: didn't Scrooge learn to be good? Commentary on Magnuson,McMurray, Tanenhaus,and Aslin (2003)

Magnuson, McMurray, Tanenhaus, and Aslin [Cogn. Sci. 27 (2003) 285] suggest that they have evidence of lexical feedback in speech perception, and that this evidence thus challenges the purely feedforward Merge model [Behav. Brain Sci. 23 (2000) 299]. This evidence is open to an alternative explanation, however, one which preserves the assumption in Merge that there is no lexical–prelexical feedback during on‐line speech processing. This explanation invokes the distinction between perceptual processing that occurs in the short term, as an utterance is heard, and processing that occurs over the longer term, for perceptual learning.     

Spectral factors in the perception of vowel quantity in Icelandic

Previous research has shown that the ratio of vowel to rhyme (vowel + consonant) duration is a major cue for quantity in Icelandic. In particular it serves as a higher-order invariant which enables the listener to disentangle those durational transformations of the speech signal which are "extrinsic" (e. g. due to changes in speaking rate) from those which are "intrinsic" to the phonemic message, involving a change of phonemic quantity. Previous research has been based on speech segment contrasts which are purely durational, involving vowels with a uniform spectrum whether phonemically long or short, such as [a] or [I]. This paper looks at the role of spectral factors in vowels which are spectrally dissimilar in their long and short varieties. It is shown that in these cases the spectral differences can be sufficiently great to override the previously established relational invariant for quantity. The implications of this finding for a model of quantity perception are discussed.     

Maternal perception of infant intentionality at 4 and 8 months

This study examines the degree to which mothers perceive infants as intentional and the relations among perception of intentionality, background variables, maternal emotional adjustment, and maternal interactive style. Forty mother-infant dyads were assessed when the infants were 4 months old, and 34 were retested at 8 months. Parent perception of infant intentionality (PPII) was measured via a rating of videotaped segments of infant behavior and an interview. Intentionality scores showed acceptable internal consistency and were positively intercorrelated at each age and across age. The two measures were aggregated to form an index of PPII at each age. Higher educational attainment was associated with lower PPII scores, experience with infants was associated with higher PPII scores, and academic knowledge about child development was not related to PPII. Mothers with more symptoms of anxiety had lower PPII scores, but high maternal separation anxiety was associated with higher PPII scores. Maternal symptoms of depression had a complex relation to PPII scores. Mothers rated as sensitive in mother-infant interactions had higher PPII scores. These variables accounted for 34% of the variance in PPII at 4 months and 49% at 8 months. There were also group differences: Mothers of 8-month-olds had higher PPII scores than mothers of 4-month-olds, mothers of girls had higher PPII scores than mothers of boys, and mothers attributed more intentionality in episodes with girls than in episodes with boys. The results are discussed in relation to mechanisms whereby PPII interacts with aspects of the parent and infant.

The empirical relationships of the religious orientations to personality

The aim of this study was to investigate the relationships between the religious orientations and the psychoanalytic character types, as assessed by the Basic Character Inventory (BCI). A person with an intrinsic religious orientation is sincere and integrated in his religiousness. A person with an extrinsic religious orientation uses his religion to promote his personal, social and economic goals. A person with a quest religious orientation is seeking, doubting and changeable in his religiousness. In a sample of 471 subjects, 168 men and 303 women, the level of intrinsic religious orientation was not related to the BCI scores. The levels of extrinsic and quest religious orientations were positively related to the BCI Oral score. Since the oral persons are dependent and craving, it seems likely that they may be extrinsically oriented. And as they also may be insecure, vague and indecisive, it is not unexpected that they also are quest oriented. The changeable quest orientation was also positively related to the changeable BCI Hysterical character.     

On stability of the structure of implicit personality theory over situations

In the present study, the following (hitherto unaddressed) question was posed: “Is the structure of implicit personality theory stable over situations?”. In order to answer this question, correlation coefficients were computed between different aspects of two trait-structures obtained under different situational conditions. The results seem to indicate that the structure of IPT is stable over situations. The results are discussed in the light of some methodological considerations.     

Development of manipulatory skills and the deployment of attention

Two independent tasks, object manipulation and auditory-visual matching, were used to examine the relationship between developing manual action skills and attention to intermodal object properties in 3.5- and 5.5-month-olds. Although handling skills improved with age, with older infants demonstrating more varied manipulation, there were no age differences for the matching task. When grouped by handling skills, a significant interaction between skill and event type was found for the two age groups combined and for 5.5-month-olds alone. Auditory-visual matching of social events did not vary with handling skills, whereas auditory-visualmatching of object events did. Infants at higher skill levels responded similarly to social and object events, whereas less skilled infants' matching preferences were weaker for object events. These findings indicate that infants increase their attention to auditory and visual properties of objects as this information becomes useful for guiding new actions. This effect is independent of age due to considerable individual variability in the development of object handling skills.     

Cognitive influences on cross-language speech perception in infancy

Previous research has shown that young infants can discriminate both native and nonnative phonetic contrasts with ease. By 10 to 12 months of age, however, infants—like adults—typically have difficulty discriminating consonant contrasts that are not used to distinguish meaning in their native language. Although the timing of this change in speech perception has been firmly established, little is currently known about the processes or mechanisms involved in this selective and adaptive reorganization in nonnative phonetic discrimination. This study was designed to determine if there is a relation between age-related changes in speech perception performance and other developing cognitive abilities. A total of 40 8- to 10-month-old infants were tested on a nonnative consonant discrimination task and then on two additional tasks (a visual categorization task and an object search task) in an attempt to determine whether changes in nonnative consonant perception coincide with changes in these other areas of cognitive/perceptual functioning. The results indicate that changes in task performance occur in synchrony across all three tasks, and that this synchrony is not explained by simple age effects. These findings suggest that domain-general cognitive/perceptual competencies may influence developmental changes in speech perception by the end of the 1st year of life.
