How early does morpholexical reading develop in readers of a shallow orthography?

In this research, lexical and morpholexical reading in Italian children ages 8 to 10 years were investigated. Children and control adults were administered two tasks on words and pseudowords: visual lexical decision and naming. Word frequency effects in both lexical decision and naming were found in both children and adults. For all age groups pseudowords made up of roots and derivational suffixes were decided more frequently as possible words and were named more quickly and accurately than matched pseudowords with no morphological constituency. These results show that morpholexical reading is available and efficient in young readers of a shallow orthography, with similar patterns in children and adults.     

Does awareness of speech as a sequence of phones arise spontaneously?

It was found that illiterate adults could neither delete nor add a phone at the beginning of a non-word; but these tasks were rather easily performed by people with similar environment and childhood experiences, who learned to read rudimentarily as adults. Awareness of speech as a sequence of phones is thus not attained spontaneously in the course of general cognitive growth, but demands some specific training, which, for most persons, is probably provided by learning to read in the alphabetic system.     

Does echoic memory develop?

A series of experiments is reported on the stimulus suffix effect with the primary variables being age of the subject (7 and 11 years), rate of presentation, and list length. While the suffix effect was larger for younger subjects at a slow rate of presentation, the effect was nearly identical across age groups with a fast presentation rate. It was concluded that when the contaminating effects of more central processes are reduced, there is no developmental change in the capacity of echoic memory. An interesting effect of rate of presentation is reported with younger subjects performing better at faster rates of presentation and adults performing better at slower rates.

Does interword spacing influence lexical processing in Chinese reading?

This study investigated how inserting spaces between Chinese words affected word recognition in Chinese reading. Eye movements of Chinese readers were recorded in a sentence reading task where high- and low-frequency target words were presented in both the spaced and normally unspaced texts. We found that fixation durations on target words were shorter in the high- than low-frequency conditions, and shorter in the spaced than unspaced conditions. The survival analysis revealed that interword spacing advanced the temporal onset of word frequency effects relative to the normally unspaced condition. However, inconsistent with the findings in English reading, there was no interaction between word frequency and interword spacing on all fixation duration measures, and the Bayes factor analyses also favoured the hypothesis of null interaction. These data suggest that interword spacing facilitates visual rather than lexical processing in Chinese reading, and thus improves our understanding on the roles of interword spacing across different writing systems.

Does conceptual implicit memory develop? The role of processing demands

The author investigated the importance of processing considerations within implicit memory in a developmental design. Second-graders (n = 87) and college students (n = 81) completed perceptual (word stem completion) and conceptual (category generation) implicit memory tests after studying target items either nonsemantically (read) or semantically (generated). In support of previous research, the author found no age differences in priming in the nonsemantic study/perceptual test condition. Age differences in priming were found in the semantic study/conceptual test condition, however, where college students had significantly higher priming scores than did children. These developmental dissociations support the theory that the processing requirements of conceptual implicit memory are similar to those in explicit memory. The author also discusses the contribution of the Transfer Appropriate Processing (TAP; H. L. Roediger, D. A. Gallo, & L. Geraci, 2002) framework to understanding these findings.     

Did Darwin initially develop a theory of evolution in the biological sense of the word?

Abstract

Darwin’s physicalist orientation reacts to a long-standing vitalistic mode of thought of idealistic morphology and should be assessed by taking other 19th and 20th centuries biological schools of thought into account - trends that each emphasised different modes of explanation, such as mechanicism, physicalism, holism, neo-vitalism, organismic biology and pan-psychism.

Darwin’s acceptance of “universal laws of nature” is consonant with Leyll’s view of invariant natural laws (uniformitarianism), but at the same time, owing to their tendency towards change, living entities are considered to be without constant structures - an outcome of Darwin’s nominalist understanding of living entities. Nominalism provides a starting point both for modem historicism (with its emphasis on change) and for Darwin’s adherence to a nominalistic view of living entities. In the light of the fossil record, the issue of constancy and change is discussed with a focus on Gould’s claim that the basic theory of natural selection offers no statement about general progress and therefore does not supply a mechanism in terms of which an overall advance might be expected.

Darwin’s physicalistic orientation in 1859 made it problematic for him to claim that he has accounted for evolution in the truly biological sense of the word.     

Is dependence on phonological information in children's reading a product of instructional approach?

Eight-year-old British children were found to be less accurate at rejecting pseudohomophones than ordinary nonwords in a lexical decision task, but 8-year-old New Zealand children did not show this effect. A subsequent homophone decision task showed that this difference was not due to the New Zealand children being unable to distinguish pseudohomophones from other nonwords. The New Zealand children, however, were less accurate than the British children in pronouncing the pseudohomophones they had identified. It was argued that the British children tended to sound out the items before making a choice in the lexical decision task, which gave salience to phonological rather than visual information, resulting in increased errors to the pseudohomophones. It was concluded that where the British children showed this dependency on use of phonological information it was a product of the teaching approach they had experienced.     

Motor sequence learning and reading ability: is poor reading associated with sequencing deficits?

Although it is widely assumed that children with learning disabilities have "sequencing problems," these have not been well specified. A non-verbal serial reaction time (SRT) paradigm was used to evaluate motor sequence learning in 422 children between ages 7 and 11 in relation to reading, cognitive ability level, and attention problems. The children demonstrated the response profile typically associated with motor sequence learning, but the component of the profile indicative of implicit sequence learning was not reliably associated with any of the predictors. Cognitive ability predicted overall response time; cognitive ability, reading, and attention problems each predicted overall accuracy. Explicit learning was predicted by cognitive ability, but not by reading or attention problems. Thus, we found no evidence that poor reading is preferentially associated with a domain general deficit in sequential learning.     

Difficulties in auditory organization as a cause of reading backwardness? An auditory neuroscience perspective

Over 30 years ago, it was suggested that difficulties in the ‘auditory organization’ of word forms in the mental lexicon might cause reading difficulties. It was proposed that children used parameters such as rhyme and alliteration to organize word forms in the mental lexicon by acoustic similarity, and that such organization was impaired in developmental dyslexia. This literature was based on an ‘oddity’ measure of children's sensitivity to rhyme (e.g. wood, book, good) and alliteration (e.g. sun, sock, rag). The ‘oddity’ task revealed that children with dyslexia were significantly poorer at identifying the ‘odd word out’ than younger children without reading difficulties. Here we apply a novel modelling approach drawn from auditory neuroscience to study the possible sensory basis of the auditory organization of rhyming and non‐rhyming words by children. We utilize a novel Spectral‐Amplitude Modulation Phase Hierarchy (S‐AMPH) approach to analysing the spectro‐temporal structure of rhyming and non‐rhyming words, aiming to illuminate the potential acoustic cues used by children as a basis for phonological organization. The S‐AMPH model assumes that speech encoding depends on neuronal oscillatory entrainment to the amplitude modulation (AM) hierarchy in speech. Our results suggest that phonological similarity between rhyming words in the oddity task depends crucially on slow (delta band) modulations in the speech envelope. Contrary to linguistic assumptions, therefore, auditory organization by children may not depend on phonemic information for this task. Linguistically, it is assumed that ‘book’ does not rhyme with ‘wood’ and ‘good’ because the final phoneme differs. However, our auditory analysis suggests that the acoustic cues to this phonological dissimilarity depend primarily on the slower amplitude modulations in the speech envelope, thought to carry prosodic information. Therefore, the oddity task may help in detecting reading difficulties because phonological similarity judgements about rhyme reflect sensitivity to slow amplitude modulation patterns. Slower amplitude modulations are known to be detected less efficiently by children with dyslexia.     

Does binge eating play a role in the self-regulation of moods?

Self-reported emotional experiences and eating behaviors were studied in college students in an attempt to determine what types of emotional experiences precede and follow binge eating and how specific types of compensatory behaviors modify these experiences. First-year male and female students (N=390) were surveyed for depression, anxiety, health status, life satisfaction, and eating attitudes (EAT-26). Those reporting recurrent binge eating episodes were asked to describe their emotional feelings before and after bingeing and before and after compensatory activities. EAT-26 scores corresponding to scores previously reported for eating disordered patients were found in 9.7% of students. Binge eating was nearly twice as frequent among females (16.4%) as males (8.6%) Among females, positive relationships were found between specific EAT-26 factors scores and both anxiety and depression scores. The emotional antecedents and consequences of binge eating and of compensatory activities were compared in three sub-groups of individuals who reported recurrent bingeing with loss of self-control during binges. The three sub-groups consisted of individuals who reported, 1) bingeing without engaging in compensatory activities, 2) bingeing and compensating by means other than vomiting (fasting, exercising, or use of laxatives or diuretics), and 3) bingeing and compensating by vomiting. Regardless of the type of activity, those individuals who engaged in compensatory activities reported greater negative affect preceding binge episodes than those who did not compensate. In addition, contrary to expectations, negative affect did not decrease, but instead increased significantly, following binge episodes and decreased immediately before and after compensatory activities.

The curious case of spillover: Does it tell us much about saccade timing in reading?

In completing daily activities, the eyes make a series of saccades by gazing at stimuli in succession. The duration of gaze on each stimulus has been used to infer how the initiation of a saccade is timed relative to the underlying mental processing. In reading, gaze dwells longer on a word that occurs infrequently in English text (low frequency) than on a more frequent word (high frequency), but also on the following word, which is referred to as spillover. Accounts of spillover attribute it to mechanisms of lexical access. A low-frequency word n is assumed to delay the onset of cognitive processing of word n+1 more than it delays the saccade to n+1, leaving more processing to be done on n+1 once it is fixated. We tested this assumption by having participants perform a series of speeded lexical decisions on a linear array of letter strings spaced 5° apart, using low- and high-frequency words to vary the lexical difficulty. Lexical decision adds a response selection stage that is absent in reading, which should eliminate differential effects on saccades and cognitive processing. Nonetheless, we found the typical pattern of lengthened gaze duration and spillover for low-frequency words, with effects that were consistent in magnitude with those seen in studies of reading. These data challenge existing accounts of spillover and argue against the idea that reading has a unique interaction with oculomotor control. Instead, the similarity of our gaze patterns to those of reading suggests a common pattern of saccade initiation across tasks.     

Does degree of handedness in a group of right-handed individuals affect language comprehension?

The impact of handedness on language processing has been studied extensively and the results indicate that there is a relationship between the two variables; however, the nature of the relationship is not at all clear. In the current study we explored degree of handedness (DH) opposed to direction in a group of right-handed individuals. fMRI was used to explore the impact of DH on the sentence comprehension network. The results revealed that during sentence comprehension activation in regions linked to semantic memory (e.g., anterior temporal cortex) were modulated by DH. Also, unexpectedly the precuneus/posterior cingulate gyrus which has been linked to episodic memory was also affected by DH. These results extend those reported previously by showing that the neural architecture that supports sentence comprehension is modulated by DH. More specifically, together the results presented here support the hypothesis proposed by Townsend, Carrithers, and Bever (2001) that DH interacts with the language system and impacts the strategy used during sentence comprehension.     

Measuring central executive functioning: what's in a reading span?

Although variations of Daneman and Carpenter's (1980) Reading Span Test (RST) have seen increasing use in both cognitive and neuropsychological research, the specific mental operations involved in performing it remain unclear. We tested 80 undergraduates to examine the extent to which speed of processing, manipulation capacity, and susceptibility to interference contributed to RST performance. The results suggest that, rather than unitary central executive or processing speed functions underlying RST performance, at least two factors, manipulation capacity and susceptibility to interference, underlie the task. Further study of RST operations may lead to a better understanding of the nature of the central executive itself.     

Does luck have a place in epistemology?

Some epistemologists hold that exploration and elaboration of the nature of luck will allow us to better understand knowledge. I argue this is a mistake.     

Does repeated reading predict reading development over time? A study of children from Grade 3 to 4

The purpose of this study was to investigate whether immediate gains in reading fluency achieved during repeated reading of text can predict long‐term reading development over and above traditional predictors of reading development. Eighty‐one Grade 3 children read texts three times consecutively and were instructed either to read as quickly as possible (speed‐focused repeated reading), or to retell the text afterwards (meaning‐focused repeated reading). Measures of text reading fluency, sentence reading fluency, and text comprehension were administered to the children in Grades 3 and 4 to assess their reading development over time. The results indicate that children's immediate response to repeated reading can contribute to the prediction of their development of reading fluency over time. Even after controlling for individual differences in general cognitive ability, word reading fluency, rapid automatized naming, and vocabulary, the experimental measure with meaning‐focused repeated reading remained a significant predictor.     

Does recall of a past music event invoke a reminiscence bump in young adults?

Many studies of the reminiscence bump (RB) in music invoke memories from different autobiographical times by using stimulus specific prompts (SSPs). This study investigated the utility of a non-SSP paradigm to determine whether the RB would emerge when participants were asked to recall a single memorable musical event from “a time long ago”. The presence of a RB in response to music has not been obtained in such a manner for younger participants. Eighty-eight 20–22 year olds reported music episodes that peaked when their autobiographical age was 13–14 years. Self-selected stimuli included a range of musical styles, including classical and non-Western pop forms, such as J-pop and K-pop, as well as generational pop music, such as the Beatles. However, most participants reported pop/rock music that was contemporaneous with encoding age, providing support for the utility of published SSP paradigms using pop music. Implications for and limitations of SSP paradigms are discussed. Participants were also asked to relate the selected musical piece to current musical tastes. Most participants liked the music that they selected, with many continuing to like the music, but most also reported a general broadening of their taste, consistent with developmental literature on open-earedness.
