The face you recognize may not be the one you saw: memory conjunction errors in individuals with or without learning disability

Memory conjunction errors, that is, when a combination of two previously presented stimuli is erroneously recognized as previously having been seen, were investigated in a face recognition task with drawings and photographs in 23 individuals with learning disability, and 18 chronologically age-matched controls without learning disability. Compared to the controls, individuals with learning disability committed significantly more conjunction errors, feature errors (one old and one new component), but had lower correct recognition, when the results were adjusted for different guessing levels. A dual-processing approach gained more support than a binding approach. However, neither of the approaches could explain all of the results. The results of the learning disability group were only partly related to non-verbal intelligence.     

Orthographic neighbors and visual word recognition

Two lexical decision experiments, using words that were selected and closely matched on several criteria associated with lexical access, provide evidence of facilitatory effects of orthographic neighborhood size and no significant evidence of inhibitory effects of orthographic neighborhood frequency on lexical access. The words used in Experiment 1 had few neighbors that were higher in frequency. In Experiment 2, the words employed had several neighbors that were higher in frequency. Both experiments showed that words possessing few neighbors evoked slower responses than those possessing many neighbors. Also, in both experiments, neighborhood size effects occurred even though words from large neighborhoods had more potentially interfering higher-frequency neighbors than words from small neighborhoods.     

Development of animal recognition: a difference between Parts and Wholes

A series of experiments examined children's recognition of animals by their features (Parts) and by the relative scale of the parts (Wholes). They were asked to identify the correct picture of an animal they could name from the original plus two computer-generated alternatives. We examined the developmental trends associated with upright (Studies 1 and 3) and inverted presentations (Study 3). Both experiments confirmed children's superior ability in dealing with the recognition of animal Parts over animal Wholes, especially for the younger ages tested (6- and 10-year-olds). It was not until the ages of 15-16 that children demonstrated equal performance on Whole and Part items. The late acquisition of animal Whole recognition is compared to the late acquired configural skills proposed for face recognition.     

Perceived change in quality of life among chinese canadian seniors: the role of involvement in chinese culture

Although much gerontological literature is focused on subjective well-being, quality of life, and life satisfaction, we know little about this concept in old age among sub-cultural groups. This paper presents empirical data on subjective well-being among Chinese seniors (age 55 and over) living in seven cities in Canada. It asks whether and to what extent traditional Chinese culture, a culture in which seniors have been historically valued as wise and contributing members to be respected, is related to their evaluation of whether or not life has improved in old age. Among a random sample of 2272 Chinese seniors, some but not all aspects of traditional Chinese culture were related to their valuation of old age. In particular, involvement in that traditional culture, return visits to the homeland, immigration due to family reunion, and ancestor worship were significant predictors but differentially depending on whether the overall scale or specific domains within that overall scale was the dependent variable. The fact that differential aspects of traditional culture contribute to a positive experience of aging suggests we must be careful in generalizing to traditional culture. Importantly, ethnocentric beliefs regarding Chinese culture were not related to any domain of quality of life.     

Faithful Aging and the Development of Character

The author tests the kinship of the concepts faithful aging, the centerpiece of her book, The Art of Growing Old: A Guide to Faithful Aging (1998), and development of character, central to James Hillman's book, The Force of Character and the Lasting Life (1999). Faithful aging is assessed in characters from two plays: Graham Greene's The Potting Shed and Robert Anderson's I Never Sang for My Father. Finally, Saussy reflects on the development of character as a theological issue.     

Segmentation and Selection of Appropriate Chinese Characters in Writing Place Names in Japanese

This paper explores the relation between an unknown place name written in hiragana (a Japanese syllabary) and its corresponding written representation in kanji (Chinese characters). We propose three principles as those operating in the selection of the appropriate Chinese characters in writing unknown place names. The three principles are concerned with the combination of on and kun readings (zyuubako-yomi), the number of segmentations, and the bimoraicity characteristics of kanji chosen. We performed two experiments to test the principles; the results supported our hypotheses. These results have some implications for the structure of the Japanese mental lexicon, for the processing load in the use of Chinese characters, and for Japanese prosody and morphology.     

Time course of frequency effects in spoken-word recognition: evidence from eye movements

In two experiments, eye movements were monitored as participants followed spoken instructions to click on and move pictures with a computer mouse. In Experiment 1, a referent picture (e.g., the picture of a bench) was presented along with three pictures, two of which had names that shared the same initial phonemes as the name of the referent (e.g., bed and bell). Participants were more likely to fixate the picture with the higher frequency name (bed) than the picture with the lower frequency name (bell). In Experiment 2, referent pictures were presented with three unrelated distractors. Fixation latencies to referents with high-frequency names were shorter than those to referents with low-frequency names. The proportion of fixations to the referents and distractors were analyzed in 33-ms time slices to provide fine-grained information about the time course of frequency effects. These analyses established that frequency affects the earliest moments of lexical access and rule out a late-acting, decision-bias locus for frequency. Simulations using models in which frequency operates on resting-activation levels, on connection strengths, and as a postactivation decision bias provided further constraints on the locus of frequency effects.

Hemispheric asymmetries in visual word-form processing: progress, conflict, and evaluating theories

The ubiquitous left-hemisphere advantage in visual word processing can be accounted for in different ways. Competing theories have been tested recently using cAsE-aLtErNaTiNg words to investigate boundary conditions for the typical effect. We briefly summarize this research and examine the disagreements and commonalities across the theoretical perspectives. This work may provide a good example why a multi-level, multi-method, and multi-paradigm approach holds the greatest promise for rapid theoretical progress.
