The effect of phonemic processing on the retention of graphemic representations for words and nonwords

The three experiments reported in this study were each conducted in two phases. The first phase of Experiment 1 involved a same-different comparison task requiring “same” responses for both mixed-case (e.g., MAIN main) and pure-case (e.g., near near) pairs. This was followed by Phase 2, a surprise recognition test in which a graphemic effect on word retention was indicated by the superior recognition accuracy obtained for pure-case compared with mixed-case pairs. The first phases of Experiments 2 and 3 involved pronounceability and imageability judgment tasks, respectively. Graphemic retention was assessed by contrasting recognition accuracy for letter strings presented, during Phase 2, in their original Phase 1 case, with letter strings presented, during Phase 2, in. a graphemically dissimilar new case. The experiments provided evidence that there was minimal retention of the graphemic representations from which the phonemic representations of words are generated and, further, that the locus of this effect is probably postlexical. Nonwords were recognized more accurately than words in all three experiments. The latter result was attributed to differences between nonwords and words in both graphemic retention and semantic distinctiveness.     

Illusions of familiarity caused by cohort activation

Subjects took part in an auditory lexical decision task followed by an auditory test of recognition memory for words presented in this task. Subjects categorized their recognition judgments as based on either recollection (“remember” responses) or familiarity (“know” responses). Distractor items in the recognition test included the base words from which the nonwords used in the lexical decision task were derived. Consistent with the findings of Wallace, Stewart, Sherman, and Mellor (1995), more false alarms were made to “late” base words (where the corresponding nonwords were created by changing a phoneme near the end of the word) than to “early” base words (corresponding nonwords were created by changing a phoneme at the beginning of the word). However, this effect was found in “know” responses but not in “remember” responses. The findings are attributed to enhanced fluency with which the base words are processed following their implicit activation at encoding.     

知道感（FOK）和不知道感（FOnK）的双向实验分离

为了实现FOK（feeling-of-knowing）和FonK（feeling-of-not-knowing）的双向分离,实验一采用高频词或者低频词为线索项目,检验FOK和FOnK的预测准确性。结果发现,在低频线索条件下FOK的预测准确性表现出高于FOnK的预测准确性的趋势,而在高频线索条件下则正好相反,但上述两组差异并未在统计学上达到显著的程度。实验二采用词－非词对和相关词对两种实验条件,在证明相关词对条件可以促进FOK并降低FOnK的同时,观察到词－非词条件可以促进FOnK并降低FOK,从而在较为严格的意义上证明了FOK和FOnK是两个不同的维度的量。上述结果为知道感的“双过程假设”提供了进一步的实验证据     

Remember,know, confidence and the mirror effect: Changes as a function of discriminability conditions

Recognition memory for Spanish-Catalan cognate and noncognate words was tested at retention intervals of 20 minutes, 1 hour, and 24 hours (Experiment 1) using a remember/know response procedure, and requiring a confidence judgement on the yes/no response. Noncognate words were accompanied by more “remember” responses than cognates, and overall A' was significantly different from remember A', except in the cognate condition at the longest retention interval. A strong mirror effect for the cognate-noncognate stimulus class was found for overall responding, and for high but not low confidence, indicating a differential use of recollection and familiarity in recognition. In general, the pattern of results was inconsistent with Donaldson's (1996) signal detection model, indicating that, when available, subjects use two different sources of information for discrimination. The examination of individual hits and false alarms as a function of confidence indicated that “remember” is uniformly associated with high confidence, but “know” shows a bipolar pattern. In Experiment 2, new and old words were repeated at test 2 and 3. Repetition greatly affected the difference between the discrimination indices, indicating that an increase in the familiarity of new words prevented the use of a dual source of information in recognition. Results are discussed in terms of Rajaram's distinctiveness (1996, 1998) and Reder, Nhouyvanisvong, Schunn, Ayers, Angstadt, and Hiraki's (2000) SAC theories.     

Same-different judgments with words and nonwords: The differential effects of relative size

Words were paired with words and nonwords with nonwords in a simultaneous matching task requiring a same-different judgment. A difference in size slowed “same” RTs for both words and nonwords, while “differ” RTs for both words and nonwords were unaffected. These results do not support Bruder and Silverman’s 1974 conclusion that the word processing system filters size. The effects of relative size differences were discussed in terms of (a) normalization procedures and (b) changes in states of evidence leading to alterations in a response selection stage.     

大学生对穷人的消极刻板印象及猜测偏向

主要考察大学生对穷人的消极刻板印象及猜测偏向。实验1中的两个单类内隐联想测验结果与前人研究基本一致：虽然被试对穷人热情的评价相对积极,但总体上认为穷人低能力、低热情。实验2通过源监测任务发现,在忘记特质词来源的情况下,被试倾向于猜测消极特质词来自贫困者,积极特质词来自小康者。研究不仅证实了大学生对穷人的消极刻板印象,而且进一步发现大学生存在对穷人的消极猜测偏向。     

Processing level and recognition: A search method for inducing alternative encodings of unrelated words

Twenty-four subjects viewed cards containing four words. In synonym orienting, half of the cards contained a synonym pair and half did not; in homophone orienting, half of the displays contained a homophone pair. The remaining two words in each display were used to index retention. During presentation of displays, subjects responded “yes” or “no” to indicate the presence or absence of a matching pair. Following presentation, a recognition test was administered. Half the items were tested early and half were tested late; within each test order, half the items appeared with context cues during testing and half appeared without. Results showed superior recognition (1) following semantic orienting, (2) for items tested early, (3) for items tested with context, and (4) for nonmatch displays requiring exhaustive item comparison. An Orienting by Test Cuing interaction showed that the presence of test cues improved recognition for homophone orienting items only. The interaction may have resulted from the lack of cuetarget associations and the reinstatement of the phonemic orienting set during the test.     

The modulation of semantic transparency on the recognition memory for two-character Chinese words

This study demonstrated that semantic transparency as a linguistic property modulates the recognition memory for two-character Chinese words, with opaque words (i.e., words whose meanings cannot be derived from constituent characters—e.g., “光[/guang/, light]棍[/gun/, stick]”, bachelor) remembered better than transparent words (i.e., words whose meanings can be derived from constituent characters—e.g., “茶[/cha/, tea]杯[/bei/, cup]”, teacup). In Experiment 1, the participants made lexical decisions on transparent words, opaque words, and nonwords in the study and then engaged in an old/new recognition test. Experiment 2 employed a concreteness judgment as the encoding task to ensure equivalent semantic processing for opaque and transparent words. In Experiment 3, the neighborhood size of the two-character words was manipulated together with their semantic transparency. In all three experiments, opaque words were found to be better remembered than transparent words. We concluded that the conceptual incongruence between the meanings of a whole word and its constituent characters made opaque words more distinctive and, hence, better remembered than transparent words.     

Child and adult learning of surface structure cues to deep structure using a picture card technique

An experiment requiring the learning of “new” (nonsense) words replacing the words “eager” and “easy” in the linguistic structure “John is eager/easy to please” showed that only adults and higher-IQ children could perform better than chance on the new words. Contrary to prediction, children showed no differential learning ability on two types of words to be learned. However, an analysis of the strategies used gave evidence of a language-specific learning ability in children but not in adults. It is proposed that the inability of lower-IQ children to learn the words, as well as the lack of differential learning of the two types by higher-IQ children, was due to the nature of the task-being more like that used in concept formation experiments than like natural language.     

Interactions between study task, study time, and the low-frequency hit rate advantage in recognition memory

In studies of episodic recognition memory, low-frequency words (LF) have higher hit rates (HR) and lower false alarm rates (FAR) than do high-frequency words (HF), which is known as the mirror pattern. A few findings have suggested that requiring a task at study may reduce or eliminate the LF-HR advantage without altering the LF-FAR effect. Other studies have suggested that the size of the LF-HR advantage interacts with study time. To explore such findings more thoroughly and relate them to theory, the authors conducted 5 experiments, varying study time and study task. The full mirror pattern was found only in 2 cases: the standard condition requiring study for a later memory test and a condition requiring a judgment about unusual letters. The authors explain their findings in terms of the encoding of distinctive features and discuss the implications for current theories of recognition memory and the word frequency effect.     

Semantic-memory sources of episodic retrieval failure

In a cued-recall paradigm, retrieval blocking was investigated as a source of episodic retrieval failure. Each unrelated-interference (UR-I) word pair (e.g., “nurse-dollar”) had its own “competitive alternative” (e.g., “doctor’), which not only was strongly related to the cue word, but also possessed the same first two letters and final letter as did the target word. None of the unrelated-control (UR-C) word pairs (e.g., “clock-dollar”) had such an alternative. Cued recall substantially increased from the cue-word-only (e.g., “nurse- ”) to the three-letters-also cue condition (e.g., “nurse-do___r”) for the UR-C but not for the UR-I word pairs. Instead, subjects frequently reported the competitive alternatives in place of the UR-I target words in the three-letters-also cue condition. It was suggested that, relying on the primary plausibility judgment, subjects falsely accepted the competitive alternatives while the UR-I target words were blocked from retrieval by the potent retrieval of these plausible alternatives.     

Speed of emotional information processing and emotional intelligence

The present study aimed to investigate the relationship between the speed of emotional information processing and emotional intelligence (EI). To evaluate individual differences in the speed of emotional information processing, a recognition memory task consisted of two subtests similar in design but differing in the emotionality of the stimuli. The first subtest required judgment about whether an emotional facial expression in the test face was identical to one of the four emotional expressions of the same individual previously presented. The second subtest required deciding whether the test face with a neutral emotional expression was identical to one of the four neutral faces of different individuals previously presented. Mean response latencies were calculated for “Yes” and “No” responses. All latencies were correlated with other measures of processing speed such as discrimination time and time of figure recognition. However, the emotional expression recognition subtest was hypothesized to require the processing of emotional information in addition to that of facial identity. Latencies in this subtest were longer than those in the face recognition subtest. To obtain a measure of the additional processing that was called for by the emotionality of the stimuli, a subtraction method and regression analysis were employed. In both cases, measures calculated for “No” responses were related to ability EI, as assessed via a self‐report questionnaire. According to structural equation modeling, there was a moderately negative association between latent EI and the latency of “No” responses in the subtest with emotional stimuli. These relationships were not observed for “Yes” responses in the same subtest or for responses in the subtest with neutral face stimuli. Although the differences between “Yes” and “No” responses in their associations with EI require further investigation, the results suggest that, in general, individuals with higher EI are also more efficient in the processing of emotional information.     

Judgments of recency and their relation to recognition memory

Subjects went through a list of 550 high- and low-frequency words (Experiment 1) or concrete and abstract words (Experiment 2) in which individual items were repeated at lags of 5 to 30 other items. They made old versus new recognition decisions on each word and followed each "old" response with a numerical judgment of recency (JOR). Recognition judgments displayed the mirror effect. Conditionalized on recognition, JORs were shorter for low-frequency words than for high-frequency words, and shorter for concrete words than for abstract words. This was true at every lag, suggesting that recognition and JOR may have a common basis. However, recognition confidence ratings obtained in Experiment 3 proved much less sensitive than JOR to test lag. Memory models applicable to multiple judgment tasks will be needed to account for such findings.     

Emotion words and categories: evidence from lexical decision

We examined the categorical nature of emotion word recognition. Positive, negative, and neutral words were presented in lexical decision tasks. Word frequency was additionally manipulated. In Experiment 1, “positive” and “negative” categories of words were implicitly indicated by the blocked design employed. A significant emotion–frequency interaction was obtained, replicating past research. While positive words consistently elicited faster responses than neutral words, only low frequency negative words demonstrated a similar advantage. In Experiments 2a and 2b, explicit categories (“positive,” “negative,” and “household” items) were specified to participants. Positive words again elicited faster responses than did neutral words. Responses to negative words, however, were no different than those to neutral words, regardless of their frequency. The overall pattern of effects indicates that positive words are always facilitated, frequency plays a greater role in the recognition of negative words, and a “negative” category represents a somewhat disparate set of emotions. These results support the notion that emotion word processing may be moderated by distinct systems.     

Dissociating electrophysiological correlates of subjective,objective, and correct memory in investigating the emotion-induced recognition bias

Performance on tasks requiring discrimination of at least two stimuli can be viewed either from an objective perspective (referring to actual stimulus differences), or from a subjective perspective (corresponding to participant’s responses). Using event-related potentials recorded during an old/new recognition memory test involving emotionally laden and neutral words studied either blockwise or randomly intermixed, we show here how the objective perspective (old versus new items) yields late effects of blockwise emotional item presentation at parietal sites that the subjective perspective fails to find, whereas the subjective perspective (“old” versus “new” responses) is more sensitive to early effects of emotion at anterior sites than the objective perspective. Our results demonstrate the potential advantage of dissociating the subjective and the objective perspective onto task performance (in addition to analyzing trials with correct responses), especially for investigations of illusions and information processing biases, in behavioral and cognitive neuroscience studies.     

Novelty assessment in the brain and long-term memory encoding

Recent positron emission tomography (PET) studies have identified neuronal components of widespread novelty-assessment networks in the brain. We propose that the efficacy of encoding on-line information into long-term memory depends on the novelty of the information as determined by these networks, and report a test of this “novelty/encoding” hypothesis. Subjects studied a list of words. Half of the words were “familiar” by virtue of their repeated presentation to the subjects before the study of the critical list; the other half were novel, in that they had not previously been encountered in the experiment. The results conformed to the prediction of the novelty/encoding hypothesis: accuracy of explicit (episodic) recognition was higher for novel than for familiar words.     

Replacing the Moral Foundations: An Evolutionary‐Coalitional Theory of Liberal‐Conservative Differences

Moral Foundations Theory (MFT) explains liberal‐conservative differences as arising from different moral intuitions, with liberals endorsing “individualizing” foundations (Harm and Fairness) and conservatives also endorsing “binding” foundations (Authority, Respect, and Purity). We argue these labels misconstrue ideological differences and propose Evolutionary‐Coalitional Theory (ECT) as an alternative, explaining how competitive dynamics in the ancestral social environment could produce the observed ideological differences. We test ECT against MFT across three studies. Study 1 shows the so‐called “binding” orientation entails the threat‐sensitivity and outgroup antagonism predicted by ECT; that is, an authoritarian motive. Similarly, Study 2 shows the so‐called “individualizing” orientation is better described as a universalizing motive, one reflecting a broader set of moral commitments (e.g., to nature) and a broader sociality than the egocentrism implied by MFT. Study 3 provides a factor analysis reducing “binding” to authoritarianism and “individualizing” to universalism, with the latter loading against social dominance orientation (SDO). A hierarchical regression then provides additional evidence for ECT, showing this dominating motive (SDO) accounts for variance in conservatism that MFT leaves unexplained. Collectively, these three studies suggest that ECT offers a more accurate and precise explanation of the key psychological differences between liberals and conservatives.     

Positive forgetting of sentence material

This experiment investigated the positive-forgetting phenomenon with sentence material. Sets of sentences were presented to Ss with each sentence being cued “remember” or “forget” immediately following its presentation. To-be-remembered (TBR) sentences were found to be more accessible thanto-be-forgotten (TBF) sentences and uncued control sentences. Sentence connectedness was found to be an important determiner of the magnitude of the observed recall phenomenon; but differential sentence interest was not a significant factor. Using a multiple-choice recognition test, key words or phrases from the to-be-forgotten sentences were found to be equally available as key words or phrases from the to-be-remembered sentences. These results warrant an extention of Bjork’s (1970, 1972) selective-rehearsal and differential-grouping interpretation of the positive-forgetting phenomenon to encompass sentence material. Some implications of the findings for single-presentation information acquisition were noted.     

Familiarity,relative distinctiveness,and the generation effect

In Experiment 1, psychology experts and novices showed generation effects with both psychology related and other words. In Experiment 2, music experts who were sports novices and sports experts who were music novices showed a generation effect in a recognition test for all words regardless of domain (music or sports). Moreover, the effect was greater for words from the subjects’ “nonexpertise” area. In Experiments 3A and 3B, music experts showed a greater generation effect for sports words than for music words in a free recall test but only when the sports and music words were studied together. These results are inconsistent with the semantic elaboration -requirement for the generation effect that predicts less of an effect, if any, with less familiar materials. Rather, they provide evidence for the idea that the generation effect is influenced by relative distinctiveness of the to-be-remembered items.     

Facilitation of auditory word recognition

An experiment that investigated facilitation of recognition of spoken words presented in noise IS described, Prior to the test session, the subjects either read words or heard them spoken in one of two. voices while making a semantic judgment upon them. There was a large effect of auditory priming on word recognition that did not depend upon the voice (male or female) of presentation, There were much smaller, but significant, effects of prior visual experience of the words. The implications of these data for the logogen model are discussed.
