Effects of pairing stimuli with reinforcement on multiple schedule performance of children

A nonsense word was paired with reinforcement to determine if pairing affected emission of a response that produced the word in the signalled absence of reinforcement. Children were trained on a multiple schedule that consisted of a reinforcement component, conditioned reinforcement component, and control component, each set of contingencies being signalled by a different colored light. In the primary reinforcement component, lever presses produced reinforcers which, in some phases, were paired with a word. In the other two components, lever presses were not reinforced and a button was made accessible. Button presses in the conditioned reinforcement component produced the word to be (or being) paired, e.g., "yafeh", while button presses in the control component produced another word, e.g., "grunch". Button pressing increased when one of the words was being paired and decreased when pairing was discontinued, but directly related rate changes occurred also in the control component. The order of components was shown to be a contributing variable.     

Explaining inconsistencies in Shakespeare's character Henry V on the basis of the emotional undertones of his speeches

Shakespeare's character Henry V is infamous, among 20th-century analysts of drama, for his inconsistent disposition. Some analysts highlight this character's reformation and others his Machiavellian tendency to moderate his disposition in tune with changing situations. The Dictionary of Affect in Language (Whissell, 2009) was used to score the emotional undertones of words in Henry V's dialogue. Analyses of these undertones, described in terms of Pleasantness and Activation, demonstrated that the character Henry V was, in overall terms, emotionally average, that there was minimal evidence of growth or reform in him across time, and that situational factors (e.g., revelry, kingship, courtship, battle) were associated with the dramatic changes in his speeches. The character employed more passive language in private and personal situations and more active language in his (public) royal role. Four categories of Henry V's speeches (Condescension, Control, Self-definition, and the Courtship of Good Opinion), represented in both public and private discourse, reflected increasing pleasantness in emotional undertones.     

Sonority constraints on onset-rime cohesion: evidence from native and bilingual Filipino readers of English

Research in English suggests that syllables can be analyzed in terms of two subunits-the onset (defined as the initial consonant or consonant cluster) and the rime (the unit formed by the vowel and following consonant/s). This study investigated whether nonnative readers of English, which in the case of the present study were native Filipino speakers, also make use of onset-rime units, particularly when some features of their native language (namely infixation and reduplication) appear to foster no awareness of such units. In two lexical decision experiments, monosyllabic English words were presented, divided in between their first and second consonants (e.g., B LIND), at their onset-rime boundary (e.g., BL IND), or at their antibody boundary (e.g., BLI ND). Results indicated that the processes of infixation and reduplication did not affect the English word processing of native Filipino speakers. Rather, results for both native Filipino and native English speakers suggest that onsets composed of an "s + consonant" sequence (e.g., STAMP) are less cohesive than onsets comprised of a stop-liquid sequence (e.g., BLIND). It was concluded that not only may sonority constraints underlie onset cohesiveness, but that such phonetic properties may also be involved in visual word recognition.     

Children's early reading vocabulary: Description and word frequency lists

Background: When constructing stimuli for experimental investigations of cognitive processes in early reading development, researchers have to rely on adult or American children's word frequency counts, as no such counts exist for English children. Aim: The present paper introduces a database of children's early reading vocabulary, for use by researchers and teachers. Sample: Texts from 685 books from reading schemes and story books read by 5‐7 year‐old children were used in the construction of the database. Method: All words from the 685 books were typed or scanned into an Oracle database. Results: The resulting up‐to‐date word frequency list of early print exposure in the UK is available in two forms from a website address given in this paper. This allows access to one list of the words ordered alphabetically and one list of the words ordered by frequency. We also briefly address some fundamental issues underlying early reading vocabulary (e.g., that it is heavily skewed towards low frequencies). Other characteristics of the vocabulary are then discussed. Conclusions: We hope the word frequency lists will be of use to researchers seeking to control word frequency, and to teachers interested in the vocabulary to which young children are exposed in their reading material.     

Risk-Taking,Framing Effects,and Affect

This paper examines the influence of affect′s two primary dimensions, Pleasantness and Arousal, on risk-taking behaviors. In Study 1, higher levels of Arousal led subjects to pay less for insurance to protect themselves from potential losses. In Study 2, a between-subjects design examined willingness-to-pay for statistically equivalent lotteries and insurance. Higher Arousal led to higher risk-seeking expressed as higher willingness-to-pay for lotteries but lower willingness-to-pay for insurance. Higher Negative Affectivity (i.e., Unpleasantness and high Arousal) led to higher willingness-to-pay for insurance for possible losses of substantial value. Also, higher Calmness (i.e., Pleasantness and low Arousal) led to greater willingness-to-pay for lotteries. The results are interpreted in terms of two mechanisms: (i) congruency between Pleasantness and selected risk-taking decision strategy and (ii) Arousal-induced restriction in attentional capacity.     

Retrieval and comparison processes in part--whole decisions

Undergraduate students were presented with word pairs (e.g., egg-yolk) and were timed as they decided whether one word named part of the thing named by the other word. In Experiment 1, "no" responses to nonpart pairs (e.g., fish-flaps) were slowed by the similarity of the stimulus part (flaps) to a part that the stimulus object did possess (fins). This suggested that decisions were made by retrieving parts of the stimulus object from memory and comparing them to the stimulus part. Whereas the parts used as stimuli in Experiment 1 were nonspecific, belonging to several different types of object (e.g., wheel), those selected for Experiment 2 were specific to a single type of object (e.g., thumb). In Experiment 2, "no" responses to nonpart pairs (e.g., foot-thumb) were slowed by similarity of the stimulus object (foot) to an object that the stimulus part (thumb) belonged to (hand). This suggested that decisions were made by retrieving the object to which the stimulus part belonged and comparing it to the stimulus object. The results support a hybrid model of part-whole decisions that includes directed retrieval of relational knowledge from memory and a comparison process.     

Automatic access of the meanings of ambiguous words in context: Some limitations of knowledge-based processing

Five experiments are described on the processing of ambiguous words in sentences. Two classes of ambiguous words (noun-noun and noun-verb) and two types of context (priming and nonpriming) were investigated using a variable stimulus onset asynchrony (SOA) priming paradigm. Noun-noun ambiguities have two semantically unrelated readings that are nouns (e.g., PEN, ORGAN); noun-verb ambiguities have both noun and verb readings that are unrelated (e.g., TIRE, WATCH). Priming contexts contain a word highly semantically or associatively related to one meaning of the ambiguous word; nonpriming contexts favor one meaning of the word through other types of information (e.g., syntactic or pragmatic). In nonpriming contexts, subjects consistently access multiple meanings of words and select one reading within 200 msec. Lexical priming differentially affects the processing of subsequent noun-noun and noun-verb ambiguities, yielding selective access of meaning only in the former case. The results suggest that meaning access is an automatic process which is unaffected by knowledge-based (“top-down”) processing. Whether selective or multiple access of meaning is observed largely depends on the structure of the ambiguous word, not the nature of the context.     

Individual differences among children in spelling and reading styles

Previous studies have found differences among children in their relative reliance on spelling-sound rules and word-specific associations in reading words. Children at one end of the continuum ("Phoenicians") rely heavily on spelling-sound rules; children at the other end ("Chinese") are more likely to use specific associations. This study found evidence for a Phoenician-Chinese continuum in spelling as well as in reading. Ability to spell nonsense word (e.g., "prunt") correlated more highly with ability to spell regular words (e.g., "grunt") than with ability to spell exception words (e.g., "front"). Children who were skilled at rules tended to overgeneralize them to exception words. In addition, a measure of rule use in spelling correlated with measures of rule use in reading.     

The independence of letter identity and letter doubling in reading

The ability to read requires processing the letter identities in the word and their order, but it is by no means obvious that our long-term memory representations of words spellings consist of only these dimensions of information. The current investigation focuses on whether we process information about another dimension—letter doubling (i.e., that there is a double letter in WEED)—independently of the identity of the letter being doubled. Two experiments that use the illusory word paradigm are reported to test this question. In both experiments, participants are more likely to misperceive a target word with only singleton letters (e.g., WED) as a word with a double (e.g., WEED) when the target is presented with a distractor that contains a different double letter (e.g., WOOD) than when the distractor does not contain a double letter (e.g., WORD). This pattern of results is not predicted by existing computational models of word reading but is consistent with the hypothesis that written language separately represents letter identity and letter doubling information, as previously shown in written language production. These results support a view that the orthographic representations that underlie our ability to read are internally complex and suggest that reading and writing rely on a common level of orthographic representation.     

Can language do the driving? The effect of linguistic input on infants' categorization of support spatial relations

Two experiments explored the effect of linguistic input on 18-month-olds' ability to form an abstract categorical representation of support. Infants were habituated to 4 support events (i.e., one object placed on another) and were tested with a novel support and a novel containment event. Infants formed an abstract category of support (i.e., looked significantly longer at the novel than familiar relation) when hearing the word "on" during habituation but not when viewing the events in silence (Experiment 1) or when hearing general phrases or a novel word (Experiment 2). Results indicate that a familiar word can facilitate infants' formation of an abstract spatial category, leading them to form a category that they do not form in the absence of the word.     

AN EXTENDED BASIC SIGHT VOCABULARY FOR THE PRIMARY GRADES

Extant word lists are typically based on word frequency counts from various types of literature (e.g., basal readers, content textbooks, trade books, adult reading material). The word list described in this study was constructed by determining what words are commonly known (i.e., recognized in their written form) by beginning readers. Almost 7,000 primary grade children were tested for basic sight recognition of 1,800 high frequency words. Using a 90 percent minimum criterion (i.e., 90 percent or more of the students at each grade level recognized each word), a 1,683‐word list was established that consisted of 587 first‐grade words, 861 second‐grade words, and 235 third‐grade words. Implications and uses of the extended basic sight vocabulary are also discussed.     

Exploring the role of lexical stress in lexical recognition

Three cross-modal priming experiments examined the role of suprasegmental information in the processing of spoken words. All primes consisted of truncated spoken Dutch words. Recognition of visually presented word targets was facilitated by prior auditory presentation of the first two syllables of the same words as primes, but only if they were appropriately stressed (e.g., OKTOBER preceded by okTO-); inappropriate stress, compatible with another word (e.g., OKTOBER preceded by OCto-, the beginning of octopus), produced inhibition. Monosyllabic fragments (e.g., OC-) also produced facilitation when appropriately stressed; if inappropriately stressed, they produced neither facilitation nor inhibition. The bisyllabic fragments that were compatible with only one word produced facilitation to semantically associated words, but inappropriate stress caused no inhibition of associates. The results are explained within a model of spoken-word recognition involving competition between simultaneously activated phonological representations followed by activation of separate conceptual representations for strongly supported lexical candidates; at the level of the phonological representations, activation is modulated by both segmental and suprasegmental information.     

Phonologically mediated priming of preexisting and new associations in young and older adults

In 2 experiments, the authors investigated phonologically mediated priming of preexisting and new associations in word retrieval. Young and older adults completed paired word stems with the first word that came to mind. Priming of preexisting associations occurred when word-stem pairs containing homophones (e.g., beech-s____) showed more completions with the target (e.g., sand) relative to unrelated pairs (e.g., batch-s____), with more priming for subordinate than for dominant homophones. Priming occurred for new associations independent of dominance such that word-stem pairs containing homophones (e.g., beech-l____ and beach-l____) were completed with the same word (e.g., laugh) more often than unrelated pairs (e.g., beech-l____ and batch-l____). No age differences in phonologically mediated priming were found for either type of association, suggesting age equivalence in the use of bottom-up phonological connections.     

Phonological priming and orthographic analogies in reading

Recent work has demonstrated that children can use orthographic analogies between the spelling patterns in words to help in decoding new words (e.g., using beak to read peak; Goswami, 1986, 1988). However, one objection has been that these analogy effects may be due to phonological priming. Two experiments examined the phonological priming alternative. In Experiment 1, a single word reading task compared the use of analogies to read words that shared both orthography and phonology (e.g., most-post), that shared orthography only (e.g., most-cost), or that shared phonology only (e.g. most-toast--the phonological priming condition). Limited effects of phonological priming were found. Experiment 2 then presented the same words embedded in prose passages--"real reading." While the orthographic analogy effect remained robust, the small phonological priming effect disappeared. It is argued that phonological priming is an insufficient explanation of the analogy effect at the single word level, and plays no role in the use of analogies in story reading.     

Test of the phonological recoding hypothesis using a letter-delay task

In some English words is a silent letter in the letter strings, e.g., PSALM. This type of word provides room to manipulate phonological similarity against the words with a nonsilent letter in the corresponding position, e.g., PASTA, to test the phonological recoding hypothesis. Letter strings excluding the silent letter or the sounding letter, e.g., _salm and a phonological condition, _asta as an orthographic condition, were presented. A "psalm-type word" was processed faster than pasta-type word," indicating that phonology plays a leading role in word recognition.     

Semantic satiation and lexical ambiguity resolution.

This study examines the effects of semantic satiation on lexical ambiguity resolution. On a given trial, participants were presented with a word triad. The first word (e.g., HEART) was presented on average 2.5, 12.5, or 22.5 times, and then participants received 2 new words for relatedness judgments. The first of the two new words was always a homograph (e.g., "ORGAN") and the other word was a related or unrelated pairmate (e.g., "KIDNEY"). In Experiment 1, when blocks of trials were intermixed with concordant (e.g., "HEART-ORGAN-KIDNEY"), discordant (e.g., "PIANO-ORGAN-KIDNEY"), and neutral (e.g., "CEILING-ORGAN-KIDNEY") trials, participants did not produce evidence of semantic satiation. In a second experiment in which only concordant and neutral trials were presented, however, participants did produce evidence of semantic satiation in the concordant condition. Taken together, Experiments 1 and 2 indicate that semantic satiation of the context-appropriate meaning of a homograph may impede ambiguity resolution.     

Phonographic neighbors,not orthographic neighbors,determine word naming latencies

The orthographic neighborhood size (N) of a word—the number of words that can be formed from that word by replacing one letter with another in its place—has been found to have facilitatory effects in word naming. The orthographic neighborhood hypothesis attributes this facilitation to interactive effects. A phonographic neighborhood hypothesis, in contrast, attributes the effect to lexical print-sound conversion. According to the phonographic neighborhood hypothesis, phonographic neighbors (words differing in one letter and one phoneme, e.g., stove and stone) should facilitate naming, and other orthographic neighbors (e.g., stove and shove) should not. The predictions of these two hypotheses are tested. Unique facilitatory phonographic N effects were found in four sets of word naming mega-study data, along with an absence of facilitatory orthographic N effects. These results implicate print-sound conversion—based on consistent phonology—in neighborhood effects rather than word-letter feedback.     

Part-whole relationships in the processing of small visual patterns

Subjects seem to react to a word faster than they react to a letter within a word. One interpretation is that words are processed holistically; another is that all visual stimuli are processed in terms of components, but that more stimulus information is available for use when the targets are words than when they are letters within words. The results of three experiments indicate that the word or pattern-level advantage occurs even when the stimulus information in the two situations is equated, but if the perceptual arrays cannot be unitized (e.g., consonant sequences), a pattern-level advantage does not occur. In addition, the experiments provide substantial evidence to indicate that if letter arrays cannot be unitized, then they are processed on a componentby-component basis, rather than holistically. Finally, the appropriate definition ofholistic processing is considered.     

In search of perceptual influences of sentence context on word recognition

A major issue in the study of word perception concerns the nature (perceptual or nonperceptual) of sentence context effects. The authors compared effects of legal, word replacement, nonword replacement, and transposed contexts on target word performance using the Reicher-Wheeler task to suppress nonperceptual influences of contextual and lexical constraint. Experiment 1 showed superior target word performance for legal (e.g., "it began to flap/flop") over all other contexts and for transposed over word replacement and nonword replacement contexts. Experiment 2 replicated these findings with higher constraint contexts (e.g., "the cellar is dark/dank") and Experiment 3 showed that strong constraint contexts improved performance for congruent (e.g., "born to be wild") but not incongruent (e.g., mild) target words. These findings support the view that the very perception of words can be enhanced when words are presented in legal sentence contexts.     

Gender and personality differences in conceptions of love: An interpersonal theory analysis

Three studies tested predictions derived from interpersonal theory regarding the relations among gender, personality, and conceptions of love. It was predicted that women would conceptualize love in terms of its nurturant varieties, namely companionate kinds of love, whereas men would conceptualize love in terms of non‐nurturant varieties, namely passionate kinds of love. Only the latter prediction received consistent support. Both women and men held a companionate conception of love, with the exception that women assigned higher ratings to friendship love and sisterly love. Regarding personality, it was predicted that high‐nurturance traits (e.g., warm‐agreeable) would be associated with a companionate conception of love whereas low‐nurturance traits (e.g., cold‐hearted) would be associated with a passionate conception of love. Results supported predictions. It was concluded that women's and men's conceptions of love are more similar than has been assumed and that the two robust interpersonal dimensions of dominance and nurturance hold considerable promise for integrating the literature on personality and gender differences in love.
