“…Word imageability (the ease with which a mental image can be formed to a word) is closely correlated with word concreteness (the extent to which words refer to objects or people; Gilhooly & Logie, 1980;Paivio, Yuille, & Madigan, 1968;rs .83 and .78, respectively). Despite these high correlations, Bird, Franklin, and Howard (2001) point out that imageability is a better predictor of picture-naming performance than is concreteness (see also Nickels & Howard, 1995). This may be because the pictures, by their very nature, are highly concrete items (they are objects or people) and this produces ceiling effects that limit concreteness's predictive power.…”

Communication using icons is now commonplace. It is therefore important to understand the processes involved in icon comprehension and the stimulus cues that individuals utilize to facilitate identification. In this study, we examined predictors of icon identification as participants gained experience with icons over a series of learning trials. A dynamic pattern of findings emerged in which the primary predictors of identification changed as learning progressed. In early learning trials, semantic distance (the closeness of the relationship between icon and function) was the best predictor of performance, accounting for up to 55% of the variance observed, whereas familiarity with the function was more important in later trials. Other stimulus characteristics, such as our familiarity with the graphic in the icon and its concreteness, were also found to be important for icon design. The theoretical implications of these findings are discussed, with particular emphasis on the parallels with picture naming. The icon identification norms from this study may be downloaded from brm.psychonomic-journals .org/content/supplemental.

“…Reliable AoA effects have been reported with older adults in object naming (e.g., Hodgson & Ellis, 1998;Morrison, Hirsh, & Duggan, 2003) and word reading (e.g., Morrison et al, 2003). AoA has also been shown to be a reliable predictor of lexical processing in patient groups such as aphasics (e.g., Cuetos, Aguado, Izura, & Ellis, 2002;Nickels & Howard, 1995) and those with Alzheimer's disease (e.g., Kremin et al, 2001). Recent work has shown that AoA may even affect the retrieval of autobiographical memories; Morrison and Conway (2010) found that the AoA of the cue words used to elicit autobiographical memories predicted the ages of the participants at the time of the memories.…”

Subjective age-of-acquisition norms for 600 Turkish words from four age groups

2016

View full text Add to dashboard Cite

The main purpose of this study was to report agebased subjective age-of-acquisition (AoA) norms for 600 Turkish words. A total of 115 children, 100 young adults, 115 middle-aged adults, and 127 older adults provided AoA estimates for 600 words on a 7-point scale. The intraclass correlations suggested high reliability, and the AoA estimates were highly correlated across the four age groups. Children gave earlier AoA estimates than the three adult groups; this was true for high-frequency as well as low-frequency words. In addition to the means and standard deviations of the AoA estimates, we report word frequency, concreteness, and imageability ratings, as well as word length measures (numbers of syllables and letters), for the 600 words as supplemental materials. The present ratings represent a potentially useful database for researchers working on lexical processing as well as other aspects of cognitive processing, such as autobiographical memory.

“…In this regard it is useful to note that previous studies that have explored the relationship with picture naming accuracy in aphasic datasets have also found imageability to be a significant predictor. For example, Nickels and Howard 12 found that imageability predicted spontaneous naming performance and they attributed this finding to the richness of semantic representations for a particular word, rather than how visually imageable a specific picture is per se. The current study extends the same finding in that it suggests both spontaneous naming and therapy outcome can be predicted by the semantic richness of the word.…”

“…Participants hear a series of beeps at random time intervals (representing floors in a lift). They are asked to count the number of beeps (range, [3][4][5][6][7][8][9][10][11][12][13][14] as if they were listening to an elevator lift climbing to a specific floor and then specify at which floor the lift had arrived. A table of written numbers was provided to enable responses from participants with number-naming difficulties.…”

“…A variety of psycholinguistic factors are likely to play a role in word retrieval, including word frequency, familiarity, length, age of acquisition (AoA), operativity, imageability, and concreteness. 12,13 While word frequency has often been taken to be a particularly important variable in word retrieval, the intercorrelation of some measures has made it difficult to disentangle their specific contribution. 14 In short, aphasic naming performance can be predicted by a combination of these factors (word frequency, AoA, imageability, and length).…”
