Masked repetition and phonological priming in picture naming

We report a series of picture naming experiments in which target pictures were primed by briefly presented masked words. Experiment 1 demonstrates that the prior presentation of the same word prime (e.g.,rose-rose) facilitates picture naming independently of the target’s name frequency. In Experiment 2, primes that were homophones of picture targets (e.g.,rows-rose) also produced facilitatory effects compared with unrelated controls, but priming was significantly larger for targets with low-frequency names relative to targets with high-frequency names. In Experiment 3, primes that were higher frequency homophones of picture targets produced facilitatory effects compared with identical primes. These results are discussed in relation to different accounts of the effects of masked priming in current models of picture naming.     

The syllable’s role in speech production: Are syllables chunks, schemas, or both?

Two experiments, one using the masked priming technique combined with very brief prime exposures and the other using a new technique, the induction technique, were run in order to investigate the role of syllabic structure in speech production. Experiment 1 (masked priming) showed no effect when primes shared only the abstract syllabic structure without the phonological content, whereas the same picture stimuli produced a syllabic priming effect in Ferrand, Segui, and Grainger (1996, Experiment 4) when primes corresponded to full syllables. In contrast, the results of Experiment 2 (induction) showed that picture naming latencies were significantly faster when subjects had first read aloud a set of words with the same syllabic structure than when these words did not share the syllabic structure with the picture target. This result was also observed when the set was composed of nonwords. These results demonstrate that the abstract syllabic structure (independently of its phonological content) plays an important role in speech production depending on the task used.     

Cultural, contextual, and intrapersonal predictors of risky sexual attitudes among urban African American girls in early adolescence

The role of cultural factors in explaining sexual attitudes among African American urban girls, aged 10-13 years, was investigated in this study. The authors predicted that girls with higher school interest, family cohesion, religiosity, and behavioral self-esteem would endorse less risky sexual attitudes. Also, older girls were expected to have more risky sexual attitudes than younger girls, and girls from 1- rather than 2-parent households were expected to have more risky sexual attitudes. The authors hypothesized that ethnic identity and gender role orientations would contribute to explaining variability in sexual attitudes after controlling for contextual and intrapersonal variables. A questionnaire containing measures of the study constructs was administered to 214 girls who were participants in a substance abuse prevention program. Pretest data were used in analyses. A final regression model accounted for 23% of the variance in sexual attitudes. Age and behavioral self-esteem were significant predictors, with younger teens and teens with higher behavioral self-esteem having less risky sexual attitudes. Cultural variables contributed to explaining variation in sexual attitudes after other variables were controlled for. Higher levels of ethnic identity were associated with less risky sexual attitudes. A masculine gender role orientation was associated with more risky sexual attitudes.     

Applying the M-92, A Self-Knowledge Technique for Determining Job Aspirations and Expectations

The M-92 technique is aimed at helping teenagers become aware of: (a) the relationships between certain classic determinants such as prestige, income, and job opportunities and their system of job aspirations and/or expectations; (b) the strong and weak points in their system of information about jobs; (c) the internal structure of their system of occupational representations; and (d) possible conflicts in values or discordancies between aspirations and expectations. From a theoretical standpoint the M-92 draws directly on Coombs (1975) and Gottfredson (1981). Methodologically, it is an extension of the Hammond et al. (1988) Social Judgement Theory to the case of pair comparisons. Several concrete examples of the M-92 in use are described.     

Attentional modulation of masked repetition and categorical priming in young and older adults

Three experiments examined the effects of temporal attention and aging on masked repetition and categorical priming for numbers and words. Participants' temporal attention was manipulated by varying the stimulus onset asynchrony (i.e., constant or variable SOA). In Experiment 1, participants performed a parity judgment task and a lexical decision task in which categorical priming and repetition priming were, respectively, tested. Experiment 2 used a semantic categorization task testing categorical priming. In Experiment 3, repetition and categorical priming were tested in the same semantic categorization task with the same stimuli. The results of the three experiments showed that masked repetition priming is insensitive to manipulations of temporal attention whereas categorical priming is. Furthermore, no differences were found between young and older adults in repetition priming effects, again contrasting with the categorical priming results for which older adults were more sensitive to attentional manipulations than young adults.     

The incremental priming technique: A method for determining within-condition priming effects

A novel priming technique is applied in two experiments using an alphabetic decision and a lexical decision task to study effects of repetition, and form-related priming on letter and word recognition. The incremental priming technique consists of a gradual increase of the prime’s informational value (operationalized as prime intensity). The minimum prime-intensity level serves as a within-condition baseline for each priming condition. Thus, we can define any priming effect with respect to two baseline conditions: one is the minimum-intensity condition of the particular priming condition (within-condition baseline), and the other is a different priming condition (across-condition baseline). This double-baseline approach makes measuring of priming effects more reliable and imposes stronger constraints on our interpretations of these effects.     

Why naming takes longer than reading? The special case of Arabic numbers

Since the work of Cattell, 1885 and Cattell, 1886, it is known that the time to name an object (or a color, a geometric figure, a drawing) is longer than the time to read the name of that object. This result has been confirmed by many authors but the explanation of this phenomenon is still lacking. One good explanation of the reading–naming time difference is the uncertainty factor. Whereas words are associated with a single response name, pictures are linked to several names (the so-called “uncertainty hypothesis”). Another good explanation of this difference is the obligatory retrieval of meaning for pictures but not for words (the so-called “semantic hypothesis”). In the present experiments, subjects had to name Arabic numbers and their corresponding written names. By using Arabic numbers and their corresponding written names, we contrasted these two hypotheses proposed to explain the reading–naming time difference. We exploited the fact that Arabic numbers share a very important attribute with their corresponding written names: their uncertainty is null. Indeed, there is only one way to name 5 and five. Our results suggest that the main factor responsible for this reading–naming time difference is the uncertainty factor, since uncertainty being equal, this difference disappeared completely throughout ten (Experiment 1) and five repeated sessions (Experiment 2).     

A practical guide to time-frequency analysis in the study of human motor behavior: the contribution of wavelet transform

The authors present a practical guide for studying nonstationary data on human motor behavior in a time-frequency representation. They explain the limits of classical methods founded exclusively on the time or frequency basis and then answer those limits with the windowed Fourier transform and the wavelet transform (WT) methods, both of which are founded on time-frequency bases. The authors stress an interest in the WT method because it permits access to the whole complexity of a signal (in terms of time, frequency, amplitude, and phase). They then show that the WT method is well suited for the analysis of the interaction between two signals, particularly in human movement studies. Finally, to demonstrate its practical applications, the authors apply the method to real data.     

Development of children's mental representations: effects of age, sex, and school experience

In the present study mental representations in drawings by 158 young children, ages 2 1/2 to 6 yr. old were analysed. The aim was to investigate whether the accuracy of mental representations increased with age and how this development progressed. Also tested were whether the inferred mental representations differed for boys and girls and whether preschool experience affected the drawings. As expected, mental representation increased in complexity with age as measured by Goodenough's score, and girls' mental representations (drawings) were significantly more elaborate than boys. Moreover, attending school early seemed to affect mental representations of the 3-yr.-olds but not the 4-yr.-olds. Results are discussed in terms of internal and external factors in mental representation in drawing a man.     

Psycholinguistic norms and face naming times for photographs of celebrities in French

A set of 105 photographs of celebrities has been standardized in French on distinctiveness, proper name agreement, face agreement, age of acquisition (AoA), and subjective frequency. Statistics on the collected variables for photographs are provided. The relationships between these variables have been analyzed. Face naming latencies have also been collected for the photographs of celebrities, and several multiple regression analyses have been carried out on naming latencies and percentages of tip-of-the-tongue (TOT) phenomena. Themain determinants of naming speed included AoA, face agreement, and name agreement. In addition, AoA, together with distinctiveness and face agreement, reliably predicted the percentages of TOTs. The norms, photographs of the celebrities, and spoken naming latencies corresponding to the celebrities are available on the Internet at norms.celebrities.googlepages.com and should be of great use to researchers interested in the processing of famous people.
