The time it takes elderly and young individuals to draw pictures and write words.

20 elderly and 20 young Ss drew pictures or wrote words for picture or word stimuli. Elderly Ss had slower response initiation than young Ss, especially when drawing. Beyond this, both age groups processed picture and word stimuli similarly. Elderly and young Ss exhibited equivalent latency increases for cross-modality trials (e.g., draw a picture given a word) over within-modality trials (e.g., draw a picture given a picture), regardless of stimulus or task modality. Strong support was found for a mathematical model of these results, which assumes age-related additive slowing for input and output subprocesses but age invariance for a cross-modality transfer subprocess. However, regressing elderly on young whole-condition latencies indicated general, multiplicative slowing: a discrepancy that questions the utility of the global Brinley plot procedure in revealing the nature of age-related slowing.

Distance-dependent processing of pictures and words.

A series of 8 experiments investigated the association between pictorial and verbal representations and the psychological distance of the referent objects from the observer. The results showed that people better process pictures that represent proximal objects and words that represent distal objects than pictures that represent distal objects and words that represent proximal objects. These results were obtained with various psychological distance dimensions (spatial, temporal, and social), different tasks (classification and categorization), and different measures (speed of processing and selective attention). The authors argue that differences in the processing of pictures and words emanate from the physical similarity of pictures, but not words, to the referents. Consequently, perceptual analysis is commonly applied to pictures but not to words. Pictures thus impart a sense of closeness to the referent objects and are preferably used to represent such objects, whereas words do not convey proximity and are preferably used to represent distal objects in space, time, and social perspective.

Semantic facilitation with pictures and words.

The present experiments explored the role of processing level and strategic factors in cross-form (word–picture and picture–word) and within-form (picture–picture and word–word) semantic facilitation. Previous studies have produced mixed results. The findings presented in this article indicate that semantic facilitation depends on the task and on the subjects' strategies. When the task required semantic processing of both picture and word targets (e.g., category verification), equivalent facilitation was obtained across all modality combinations. When the task required name processing (e.g., name verification, naming), facilitation was obtained for the picture targets. In contrast, with word targets, facilitation was obtained only when the situation emphasized semantic processing. The results are consistent with models that propose a common semantic representation for both picture and words but that also include assumptions regarding differential order of access to semantic and phonemic features for these stimulus modalities.

Conceptual representation of pictures and words: Reply to Clark.

Clark (1987) offers a dual coding alternative (Paivio, 1971, 1986) to the conceptual hypothesis that Potter, Kroll, Yachzel, Carpenter, and Sherman (1986) proposed to explain the ease with which people can read and understand rebus sentences in which a picture replaces a noun. We present theoretical and empirical reasons for positing a conceptual representation that is distinct from the representation of an object's name and from a mental image of it. The hierarchical conceptual model has greater explanatory and predictive power and is more parsimonious overall than Clark's alternative.

Directed forgetting: Comparing pictures and words.

The authors investigated directed forgetting as a function of the stimulus type (picture, word) presented at study and test. In an item-method directed forgetting task, study items were presented 1 at a time, each followed with equal probability by an instruction to remember or forget. Participants exhibited greater yes–no recognition of remember than forget items for each of the 4 study–test conditions (picture–picture, picture–word, word–word, word–picture). However, this difference was significantly smaller when pictures were studied than when words were studied. This finding demonstrates that the magnitude of the directed forgetting effect can be reduced by high item memorability, such as when the picture superiority effect is operating. This suggests caution in using pictures at study when the goal of an experiment is to examine potential group differences in the magnitude of the directed forgetting effect.

Immediate and delayed recall of words and pictures.

Examined free and serial recall of words and pictures associates in 3 experiments with 156 Ss. In immediate free recall, presentation of pictorial material increased only the secondary memory component of recall, relative to conditions involving presentation of verbal materials. No such facilitation occurred in immediate serial recall. In delayed recall tests, negative recency effects were obtained only for verbal materials, in both free and serial recall. Recency effects were either nonnegative or positive with pictures as to-be-remembered material. Results are discussed in terms of the locus of word-picture differences and the adequacy of verbal memory model explanations for them.

Hemispheric differences for identification of words and nonwords in urdu-English bilinguals.

Hemispheric asymmetry was examined for Urdu-English bilinguals identifying printed Urdu words and nonwords, separated Urdu letter strings, digits, and English nonwords. In all cases, fewer errors occurred when stimuli were presented to the right visual field/left hemisphere (RVF/LH) than to the left visual field/right hemisphere (LVF/RH). Qualitative error patterns suggested that separated Urdu letter strings were processed more serially than Urdu letter strings joined to form words or pronounceable nonwords and more serially on RVF/LH than on LVF/RH trials. This qualitative laterality effect is similar to that found for Hebrew and Arabic but opposite that found for English and suggests that the qualitative manner of processing printed verbal material is influenced by language-specific factors such as scanning direction, orthographic-to-phonological mapping rules, and morphology.

Verbalization effects in discrimination learning of pictures and words.

Compared discrimination learning of pairs of pictures (line drawings) and their verbal labels as a function of various verbalization conditions in a study with 128 undergraduates. Ss either (a) verbalized each item of a pair once (condition C1) or twice (condition C2), (b) verbalized the right item 3 times and the wrong item once (condition R), or (c) verbalized the right item once and the wrong item 3 times (condition W). The R and W conditions affected discrimination learning of both pictures and words in a way predictable from frequency theory, but pictures were easier to discriminate than words in conditions C1, R, and W. It is suggested that the results reflect the joint operation of verbal frequency and visual encoding processes in picture discrimination. (French summary) (17 ref.)

Processing time and memory for pictures.

Postexposure processing of an iconic memory following the presentation of pictures of complex, colored, naturalistic scenes was assessed in 3 experiments which examined the effects of exposure duration and mask delay upon recognition memory. Ss were 50 undergraduates. Exposure durations ranged from 50 to 550 msec and mask delays from 0 to 500 msec. For exposure durations of 300 msec and longer, recognition accuracy was primarily determined by exposure duration, and mask delay had no significant effect. For exposure durations of less than 300 msec, postexposure processing continued for up to 250 msec following the offset of a target picture, and recognition accuracy was a function of total processing time (i.e., the total time separating target and mask onsets.) This reciprocity between exposure duration and mask delay was similar to that previously demonstrated for verbal materials. The processing-time/recognition memory relationship was also shown to be due to differences in initial encoding. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Within- and between-language priming differ: Evidence from repetition of pictures in Spanish-English bilinguals.

In the current study, the authors used an immediate repetition paradigm with pictures to observe whether repetition enhances word production in bilinguals. In Experiment 1, participants were asked to name pictures that were named previously in the same language (Spanish-Spanish or English-English) or in the opposite language (Spanish-English or English-Spanish). Results revealed a repetition effect both within languages and between languages. Furthermore, there was an asymmetry within language, with repetition priming being larger in Spanish than in English. Experiments 2 and 3 revealed that lag interacted with language for both within- and between-language priming. However, lag resulted in a decrease in the asymmetry for within- but not between-language priming. The results are consistent with the view that within- and between-language repetition priming are mediated by different mechanisms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Rhyme priming of pictures and words: A lexical activation account.

Orthographically/phonologically related primes have typically been found to facilitate processing of target words. This phenomenon is usually explained in terms of spreading activation between nodes for orthographically/phonologically similar words in lexical memory. The phenomenon was explored in a series of studies involving the manipulations of prime and target type (word or picture) and prime and target task (naming or categorization). Generally, the results support the lexical activation explanation. Named primes, which activate lexical memory, facilitate processing in all target tasks involving lexical access (word and picture naming and word categorization), independent of prime type. Categorized primes show the expected Prime Type?×?Relatedness interaction with word primes, which activate lexical memory, producing much more facilitation than picture primes. Finally, unlike in semantic priming studies, increased depth of processing of a word prime decreased the size of the priming effects. Apparently, initial activation levels in lexical memory are not maintained when semantic processing of the prime is required. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Morphogenesis: collagen it takes and bone it makes

The same enzyme is responsible for the activation of transforming growth factor-beta-like signalling molecules and the processing of fibrillar procollagens. This finding implicates a metalloendoprotease in the control of cell behavior and matrix assembly during morphogenesis.     

Hypermnesia for pictures and words: Testing the recall level hypothesis.

Five experiments with 150 undergraduates examined the hypothesis that hypermnesia (improved recall across repeated tests) can be predicted from cumulative recall levels. Contrary to this view, Exp I demonstrated that when the cumulative recall levels for pictures and words were equated, pictures still produced a larger hypermnesic effect. Results of Exps II and III show that varying test length (and thus recall level) had no effect on the magnitude of the hypermnesic effect. In Exp IV, Ss studied a categorized word list and then received 1 21-min test or 3 7-min tests. Results suggest that (a) similar retrieval processes are used in these 2 conditions and (b) hypermnesia in the repeated test paradigm results from Ss generating covert cues to aid item recovery across tests. Overall findings suggest that although hypermnesia is related to cumulative recall levels, various other factors (e.g., item type) modulate the magnitude of the hypermnesia by affecting item accessibility across tests. It is argued that changes in item accessibility across tests, caused by learning during testing, play a major role in producing hypermnesia in both episodic and semantic memory tasks.

False recognition of pictures versus words in Alzheimer's disease: The distinctiveness heuristic.

False recognition of semantic associates can be reduced when older adults also study pictures representing each associate. D. L. Schacter, L. Israel, and C. Racine (1999) attributed this reduction to the operation of a distinctiveness heuristic: a response mode in which participants demand access to detailed recollections to support a positive recognition decision. The authors examined patients with probable Alzheimer's disease (AD) and older adults with this paradigm. Half of the participants studied pictures and auditory words; the other half studied visual and auditory words. Older adults who studied pictures were able to reduce their false alarms compared with those who studied words only. AD patients who studied pictures were unable to reduce their false alarms compared with those who studied words only and, in fact, exhibited trends toward greater false recognition. Implications for understanding semantic memory in AD patients are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The instructive animation: Helping students build connections between words and pictures in multimedia learning.

In 2 experiments, Ss studied an animation depicting the operation of a bicycle tire pump or an automobile braking system, along with concurrent oral narration of the steps in the process (concurrent group), successive presentation of animation and narration (by 4 different methods), animation alone, narration alone, or no instruction (control group). On retention tests, the control group performed more poorly than each of the other groups, which did not differ from one another. On problem-solving tests, the concurrent group performed better than each of the other groups, which did not differ from one another. These results are consistent with a dual-coding model in which retention requires the construction of representational connections and problem solving requires the construction of representational and referential connections. An instructional implication is that pictures and words are most effective when they occur contiguously in time or space. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What it takes to forgive: When and why executive functioning facilitates forgiveness.

To establish what it takes to forgive, the present research focused on the cognitive underpinnings of the forgiveness process. We conducted four studies that examined and supported the prediction that executive functioning (a set of cognitive control processes) facilitates forgiveness. First, a correlational study revealed a positive relation between executive functioning and dispositional forgiveness (Study 1). Second, a longitudinal study demonstrated that executive functioning predicts the development of forgiveness over a period of 5 weeks after the offense (Study 2). Finally, two experiments examined when and why executive functioning facilitates forgiveness. Specifically, and in line with predictions, Studies 3 and 4 showed that executive functioning facilitates forgiveness only in the case of relatively severe (as compared with mild) offenses. Furthermore, Study 4 provided evidence for a psychological mechanism underlying the relation between executive functioning and forgiveness by demonstrating the mediating role of rumination about the offense. Implications of these findings for the literature on forgiveness and the role of executive functioning in interpersonal relationships more generally are discussed.

Recognizing words and pictures in sentence contexts: A test of lexical modularity.

Words or pictures completed sentence fragments to form coherent or incoherent sentences. Ss made lexical decisions about words and object decisions about pictures. Modality was blocked in Exp 1 and mixed in Exp 2. In both experiments there were similar effects of context for words and pictures, contrary to the hypothesis that lexical priming produces the sentence context effect. Mixed conditions produced longer response latencies than blocked conditions but did not interact with the context effect. The finding of no interaction between the effect of context and the mixed-blocked manipulation supports a version of lexical modularity in which context effects arise as a function of post-access integration processing.
