The effect of neighborhood frequency in reading: evidence with transposed-letter neighbors

Transposed-letter effects (e.g., jugde activates judge) pose serious models for models of visual-word recognition that use position-specific coding schemes. However, even though the evidence of transposed-letter effects with nonword stimuli is strong, the evidence for word stimuli is scarce and inconclusive. The present experiment examined the effect of neighborhood frequency during normal silent reading using transposed-letter neighbors (e.g., silver, sliver). Two sets of low-frequency words were created (equated in the number of substitution neighbors, word frequency, and number of letters), which were embedded in sentences. In one set, the target word had a higher frequency transposed-letter neighbor, and in the other set, the target word had no transposed-letter neighbors. An inhibitory effect of neighborhood frequency was observed in measures that reflect late processing in words (number of regressions back to the target word, and total time). We examine the implications of these findings for models of visual-word recognition and reading.     

On the time-course of adjacent and non-adjacent transposed-letter priming

We compared effects of adjacent (e.g. atricle-ARTICLE) and non-adjacent (e.g. actirle-ARTICLE) transposed-letter (TL) primes in an event-related potential (ERP) study using the sandwich priming technique. TL priming was measured relative to the standard double-substitution condition. We found significantly stronger priming effects for adjacent transpositions than non-adjacent transpositions (with two intervening letters) in behavioural responses (lexical decision latencies), and the adjacent priming effects emerged earlier in the ERP signal, at around 200-ms post-target onset. Non-adjacent priming effects emerged about 50 ms later and were short-lived, being significant only in the 250- to 300-ms time-window. Adjacent transpositions on the other hand continued to produce priming in the N400 time-window (300- to 500-ms post-target onset). This qualitatively different pattern of priming effects for adjacent and non-adjacent transpositions is discussed in the light of different accounts of letter transposition effects and the utility of drawing a distinction between positional flexibility and positional noise.     

On the role of the upper part of words in lexical access: Evidence with masked priming

More than 100 years ago, Huey (1908/1968) indicated that the upper part of words was more relevant for perception than the lower part. Here we examined whether mutilated words, in their upper/lower portions (e.g., ), can automatically access their word units in the mental lexicon. To that end, we conducted four masked repetition priming experiments with the lexical decision task. Results showed that mutilated primes produced a sizeable masked repetition priming effect. Furthermore, the magnitude of the masked repetition priming effect was greater when the upper part of the primes was preserved than when the lower portion was preserved—this was the case not only when the mutilated words were presented in lower case but also when the mutilated words were presented in upper case. Taken together, these findings suggest that the front-end of computational models of visual-word recognition should be modified to provide a more realistic account at the level of letter features.     

Embodied perception with others’ bodies in mind: Stereotype priming influence on the perception of spatial environment

It has been shown that spatial perception is not only a function of optical variables but also a function of people’s physiological potential. When this potential is reduced, either due to age or fatigue, individuals have been observed to report hills steeper and distances longer. Two studies have demonstrated that the experience of an actual reduction in capacities is not necessary. After being primed with the elderly category, young participants estimated the gradient of various pathways and that of a hill steeper (Study 1) and distances across a grassy field longer (Study 2) than their non-primed counterparts. The activation of a social category has often been found to result in stereotype-congruent behaviors. The present findings indicate that, in addition to this well-documented behavioral mimetism, this activation also leads to perceptual mimetism. I suggest that it helps facilitate social interactions by investing the partners with a shared vision of their environment.     

The development of the orthographic consistency effect in speech recognition: from sublexical to lexical involvement

The influence of orthography on children's on-line auditory word recognition was studied from the end of Grade 2 to the end of Grade 4, by examining the orthographic consistency effect [Ziegler, J. C., & Ferrand, L. (1998). Orthography shapes the perception of speech: The consistency effect in auditory recognition. Psychonomic Bulletin &Review, 5, 683-689.] in auditory lexical decision and shadowing tasks. Words with rhymes that can be spelled in two different ways (inconsistent) produced longer auditory lexical decision and shadowing times and more errors than did consistent words. A similar consistency effect was also observed on pseudowords. The observation of a general consistency effect, both for words and pseudowords, in lexical decision and in shadowing suggests a widespread influence of orthography in the children's spoken word recognition system. On exactly the same material, with adult listeners we replicated the usual pattern of an orthographic consistency effect restricted to words in lexical decision [Ventura, P., Morais, J., Pattamadilok, C., & Kolinsky, R. (2004). The locus of the orthographic consistency effect in auditory word recognition. Language and Cognitive Processes, 19, 57-95; Ziegler, J. C., & Ferrand, L. (1998). Orthography shapes the perception of speech: The consistency effect in auditory recognition. Psychonomic Bulletin &Review, 5, 683-689]. A reanalysis of the lexical decision and shadowing results of Ventura et al. [Ventura, P., Morais, J., Pattamadilok, C., & Kolinsky, R. (2004). The locus of the orthographic consistency effect in auditory word recognition. Language and Cognitive Processes, 19, 57-95.] confirmed the discrepancy between the effects of orthographic consistency in child readers and adults. A further control experiment showed that orthographic consistency effects were not present in pre-readers. Results are interpreted considering the coexistence in children's reading of a mechanism of automatic access to well-specified orthographic representations of words and the persistence of grapho-phonological decoding procedures.     

Production on hold: delaying vocal production enhances the production effect in free recall

The Production Effect (PE) represents superior memory for produced (read aloud) relative to non-produced (silently read) items. Another method of improving memory is taking a test on the study material – the Testing Effect. We evaluated the combined influence of both effects on free recall memory, using delayed vocal production, in which study words were vocally produced only after their disappearance. Such procedure involves an initial instant test since participants had to vocally retrieve the words (rather than read them aloud). In five experiments, participants were presented with study words that they were instructed to learn by no-production (reading silently), immediate production (reading aloud), delayed reading aloud, or delayed vocal production (instant retrieval). The results showed superior recall for delayed production over all other conditions. We suggest that the source of this superiority is the desirable difficulty induced by the addition of the initial test (retrieval effort) to the vocal production. The novel delayed production condition forms a superior mnemonic.     

Understanding the underlying mechanism of the spacing effect in verbal learning: a case for encoding variability and study-phase retrieval

The spacing effect refers to the mnemonic benefit of spacing repeated study events across time compared to massing (i.e. cramming) repeated study events. Due to the robustness of this finding, substantial research has been devoted to uncovering the spacing effect’s underlying mechanism. Specification of such a mechanism has been guided by consistent findings across methodologies and several experimental manipulations that serve as boundary conditions. Past reviews of the spacing effect literature have generally considered subsets of these factors but never an exhaustive set. Thus, the current review considers more comprehensively six consistent findings in the extant spacing effect literature pertaining to human memory to better discriminate among the previously proposed theories. Review of the literature provides substantial evidence indicating the need for an encoding variability mechanism [e.g. Glenberg, A. M. (1976). Monotonic and nonmonotonic lag effects in paired-associate and recognition memory paradigms. Journal of Verbal Learning and Verbal Behavior, 15, 1–16] in addition to a reminding mechanism [e.g. Benjamin, A. S., &; Tullis, J. G. (2010). What makes distributed practice effective? Cognitive Psychology, 61, 228–247].     

There is no 'truth' outside a context: implications for the teaching of analytical psychology in the 21st century

Humans are from birth embedded in a historical and contemporary context of meanings. This always constrains their theoretical and practical activities. In this paper, I will be suggesting that there are no guiding 'truths' outside such contexts. In order to understand the foundations of any concept or new idea, it is important to comprehend the context in which it is embedded. Candidates and some of their teachers have very little knowledge of the intellectual context in which Jung or any other analytic theorist wrote. As a result, the analytic 'founders' are often believed to have discovered 'truths' transcending the context of history and of everyday life. They were, however, as much creative synthesizers as pure originators. I propose that the components of all analytic theories emerge from their embeddedness. I contend, therefore, that the understandings of these components such as psychic causality, epistemology and identity formation were quite differently conceived at the time the analytic founders were working than they are today. I will give examples to show how the acceptance of this attitude is useful in inculcating a discerning approach in candidates towards traditionally accepted analytic theories and practices. This can provide them with a method to promote their individual creative development.     

Unconscious cognition isn't that smart: modulation of masked repetition priming effect in the word naming task

Masked repetition primes produce greater facilitation in naming in a block containing a high, rather than low proportion of repetition trials. [Bodner, G. E., & Masson, M. E. J. (2004). Beyond binary judgments: Prime-validity modulates masked repetition priming in the naming task. Memory & Cognition, 32, 1-11] suggested this phenomenon reflects a strategic shift in the use of masked prime as a function of its validity. We propose an alternative explanation based on the Adaptation to the statistics of the environment (ASE) framework, which suggests the proportion effect reflects adaptation of response-initiation processes to recent trial difficulty. Consistent with ASE's prediction, (1) stimuli that produce the proportion effect also produced an "asymmetric blocking effect", showing a smaller fall in response latencies of hard items than the rise of easy items when the two item types were intermixed relative to pure blocks comprised of only one item type, and (2) manipulation of prime validity was neither necessary nor sufficient to modulate the size of masked-priming effect.     

Psychological distress in patients with chronic atrophic gastritis: the risk factors,protection factors,and cumulative effect

This study aimed to examine the psychological status among Chronic Atrophic Gastritis (CAG) patients and to find the cumulative effects of risk and protective factors. A sample of 101 CAG patients completed the investigation. Hierarchical linear regression was used to find risk and protective factors, and examine the cumulative effects in risk factor index (RFI) and protective factor index (PFI). Results showed that nine symptoms from SCL-90-R were severer among CAG patients than those in adult norm. Risk factors including positive family history of cancer and higher negative life events could predict higher GSI (β = 0.206, p = 0.023; β = 0.398, p < 0.001; R² = 0.203); more household resistant, positive coping and stronger resilience were protective factors and could predict GSI negatively (β = -0.188, p = 0.020; β = -0.350, p = 0.012; β = ?0.066, p = 0.621; R² = 0.190). The GSI was positively correlated with RFI (β = 0.338, p < 0.001; R² = 0.113) and negatively related to PFI (β = ?0.378, p < 0.001; R² = 0.133). In conclusion, CAG patients suffered from various psychological distress, and the protective factors should be enhanced cumulatively to protect against psychological distress.     

Timing in a dual-task in children and adults: when the interference effect is higher with concurrent non-temporal than temporal information

This study used a dual task with participants of different levels of cognitive capacities, assessed with neuropsychological tests, to examine the attentional cost on time judgment of processing concurrent temporal and non-temporal information. Children and adults performed a temporal reproduction task with either an interfering temporal or non-temporal discrimination task. The results showed an underestimation of time in the dual task compared to the single task, the extent of which was directly linked to individual attentional capacities. However, the non-temporal task interfered more than the temporal task on the reproduced durations. Nonetheless, the temporal reproduction task equally affected performance in the non-temporal and the temporal discrimination task. These results reveal the predominant role of the cost of dual-tasking in interference effects on time judgment, and the lesser role of concurrent information, especially of temporal information. This suggests a lack of competition for attentional resources in the processing of multiple durations.
