Integrative priming occurs rapidly and uncontrollably during lexical processing

Lexical priming, whereby a prime word facilitates recognition of a related target word (e.g., nurse --> doctor), is typically attributed to association strength, semantic similarity, or compound familiarity. Here, the authors demonstrate a novel type of lexical priming that occurs among unassociated, dissimilar, and unfamiliar concepts (e.g., horse --> doctor). Specifically, integrative priming occurs when a prime word can be easily integrated with a target word to create a unitary representation. Across several manipulations of timing (stimulus onset asynchrony) and list context (relatedness proportion), lexical decisions for the target word were facilitated when it could be integrated with the prime word. Moreover, integrative priming was dissociated from both associative priming and semantic priming but was comparable in terms of both prevalence (across participants) and magnitude (within participants). This observation of integrative priming challenges present models of lexical priming, such as spreading activation, distributed representation, expectancy, episodic retrieval, and compound cue models. The authors suggest that integrative priming may be explained by a role activation model of relational integration. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

Different influences on lexical priming for integrative, thematic, and taxonomic relations

Word pairs may be integrative (i.e., combination of two concepts into one meaningful entity; e.g., fruit—cake), thematically related (i.e., connected in time and place; e.g., party—cake), and/or taxonomically related (i.e., shared features and category co-members; e.g., muffin—cake). Using participant ratings and computational measures, we demonstrated distinct patterns across measures of similarity and co-occurrence, and familiarity for each relational construct in two different item sets. In a standard lexical decision task (LDT) with various delays between prime and target presentation (SOAs), target RTs and priming magnitudes were consistent across the three relations for both item sets. However, across the SOAs, there were distinct patterns among the three relations on some of the underlying measures influencing target word recognition (LSA, Google, and BEAGLE). These distinct patterns suggest different mechanisms of lexical priming and further demonstrate that integrative relations are distinct from thematic and taxonomic relations.

Clever and crude but not kind: Narcissism, self-esteem, and the self-reference effect

According to the agency model of narcissism (Campbell, Brunell, & Finkel, 2006) narcissists view themselves as high on agentic traits but low on communal traits. To test if this self-view extends to recall, two experiments examined the extent to which narcissism was associated with self-ratings and recall of agentic and communal traits that varied in valence. Across both experiments a trait description task was followed by a surprise recall task for the trait words and then completion of the Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988). Within the self-reference condition narcissism was related to higher selection in the trait description task and to higher recall of positive-agentic (e.g., clever) traits. This general pattern of results occurred for narcissism even while controlling for the related personality variables of self-esteem, agency, and communion. In contrast to narcissism, within the self-referent group self-esteem predicted higher recall for positive-communal traits (e.g., kind) but lower recall for negative-communal traits, a finding consistent with mnemic neglect. Overall, results supported the agency model of narcissism and extended this model to suggest that narcissists rate themselves more highly not only on positive-agentic traits but also on negative-communal traits.

An asymmetric effect of relational integration on recognition memory

Two experiments assessed whether conceptual relations (e.g., contains: cookie jar) facilitate the retrieval of concepts (e.g., cookie and jar) from long-term memory. The CARIN model of nominal combination asserts that conceptual relations are represented with and selected from the modifier noun (cookie). Thus, the model predicts that relational integration will facilitate memory for modifiers but not for head nouns (jar). In Experiment 1, concepts were studied in pairs and were then tested individually. Recognition accuracy was higher for modifiers than for head nouns. In Experiment 2, the studied concepts (e.g., cookie jar) were tested in the context of a new pair that instantiated either the same relation (e.g., cookie plate) or a different relation (e.g., cookie crumb). Recognition was again better for modifiers than for head nouns, but only when the same conceptual relation was instantiated at both study and test. Thus, results indicate that conceptual relations (a) facilitate recognition memory, and (b) are associated more strongly with the modifier than with the head noun.

Relational processing in conceptual combination and analogy

We evaluate whether evidence from conceptual combination supports the relational priming model of analogy. Representing relations implicitly as patterns of activation distributed across the semantic network provides a natural and parsimonious explanation of several key phenomena observed in conceptual combination. Although an additional mechanism for role resolution may be required, relational priming offers a promising approach to analogy.

Convergent and divergent thinking in verbal analogy

Individual differences in convergent and divergent thinking may uniquely explain variation in analogical reasoning ability. Across two studies we investigated the relative influences of divergent and convergent thinking as predictors of verbal analogy performance. Performance on both convergent thinking (i.e., Remote Associates Test) and divergent thinking (i.e., Alternative Uses Task) uniquely predicted performance on both analogy selection (Studies 1 and 2) and analogical generation tasks (Study 2). Moreover, convergent and divergent thinking were predictive above and beyond creative behaviours in Study 1 and a composite measure of crystallised intelligence in Study 2. Verbal analogies in Study 2 also varied in semantic distance, with results demonstrating divergent thinking as a stronger predictor of analogy generation for semantically far than for semantically near analogies. Results thus further illuminate the link between analogical reasoning and creative cognition by demonstrating convergent and divergent thinking as predictors of verbal analogy.

Narcissism, self-esteem, and the phenomenology of autobiographical memories

ABSTRACT Across two studies, we investigated the influence of narcissism and self-esteem along with gender on phenomenological ratings across the four subscales of the Autobiographical Memory Questionnaire (AMQ; impact, recollection, rehearsal, and belief). Memory cues varied in valence (positive vs. negative) and agency (agentic vs. communal). In Study 2, we used different memory cues reflecting these four Valence by Agency conditions and additionally investigated retrieval times for the autobiographical memories (AMs). Results were consistent with the agency model of narcissism [Campbell, W. K., Brunell, A. B., & Finkel, E. J. (2006). Narcissism, interpersonal self-regulation, and romantic relationships: An agency model approach. In E. J. Finkel & K. D. Vohs (Eds.), Self and relationships: Connecting intrapersonal and interpersonal processes. New York, NY: Guilford], which characterises narcissists as being more concerned with agentic (self-focused) rather than communal (other-focused) positive self-relevant information. Narcissism predicted greater phenomenology across the four subscales for the positive-agentic memories (Study 1: clever; Study 2: attractive, talented) as well as faster memory retrieval times. Narcissism also predicted greater recollection and faster retrieval times for the negative-communal AMs (Study 1: rude; Study 2: annoying, dishonest). In contrast, self-esteem predicted greater phenomenology and faster retrieval times for the positive-communal AMs (Study 1: cooperative; Study 2: romantic, sympathetic). In both studies, results of LIWC analyses further differentiated between narcissism and self-esteem in the content (word usage) of the AMs.

Neural dysfunction in ADHD with Reading Disability during a word rhyming Continuous Performance Task

BACKGROUND Attention-Deficit/Hyperactivity Disorder (ADHD) is a heterogeneous, neurodevelopmental disorder which co-occurs often with Reading Disability (RD). ADHD with and without RD consistently have higher inattentive ratings compared with typically developing controls, with co-occurring ADHD and RD also demonstrating impaired phonological processing. Accordingly, inattention has been associated with greater phonological impairment, though the neural correlates of the association are poorly understood from a functional neuroimaging perspective. It was postulated that only the co-occurring subgroup would demonstrate hypoactivation of posterior, left hemispheric, reading-related areas and, to a lesser extent, alterations in right hemispheric, attention areas compared with controls. METHODS A novel word rhyming Continuous Performance Task assesses functional activation differences in phonology- and attention-related areas between three groups: ten boys with ADHD and RD, fourteen boys with ADHD without RD, and fourteen typically developing controls. Subjects respond to words that rhyme with a target word as mono- and disyllabic, English words are visually presented over 90s blocks. RESULTS Behavioral performance was not different between groups. Some hypoactivation of left hemispheric, reading-related areas was apparent in ADHD and RD, but not ADHD without RD, compared with controls. Right hemispheric, attention areas showed alterations in both ADHD subgroups relative to controls; however, the differences for each subgroup were dissimilar. CONCLUSIONS The dorsal decoding subnetwork may not be grossly compromised in ADHD with Reading Disability. The role of cognitive impairments, including the level of inattention, on phonology requires clarification from a neuroimaging perspective.

Narcissism and Memory

Grandiose narcissism (characterized by an inflated sense of self) uniquely influences the encoding and retrieval of information important to one’s identity including evaluative feedback, self-related traits, and life events. Depending on both the valence (positive or negative) and the agency (self- vs. other-focused) of the information or events, narcissists’ memories may be more vivid, suppressed, or distorted. This chapter summarizes prior research on narcissism and memory as well as more recent studies focusing on the role of attention biases in the encoding of self-related traits and memories. Overall, studies support the agency model of narcissism’s prediction of attention biases and memorial enhancement for positive-agentic (e.g., clever, talented) rather than positive-communal (e.g., cooperative, sympathetic) events or information. However, results are mixed for the attention to and encoding of negative-agentic traits/events (e.g., shameful, stupid) and may depend on the extent to which the information is ego-threatening as well as the subtype of narcissism (vulnerable or grandiose).

Novel reading index for identifying disordered reading skill development: A preliminary study

ABSTRACT Children with ADHD are at high risk of developing a Reading Disability (RD), although the reasons remain unclear. ADHD-associated impairments, including processing speed, can complicate clinical evaluation for a co-occurring RD diagnosis. We propose a novel metric to (a) assess reading development and (b) provide an alternative method to classifying readers that may aid investigations for etiologies of RD in ADHD. Specifically, as both phonological decoding and word recognition skills are important precursors of reading fluency, we propose a new quantitative method comparing these skills after accounting for variations in perception, motor response, or processing speeds. Forty boys (14 control, 15 ADHD, 11 ADHD/ + RD) completed a lexical decision task testing decoding and another assessing word recognition. Response time data was modeled using a Drift Diffusion approach to estimate the underlying reading skills. Using these reading skill estimates, we calculated a novel Reading Tendency Index and classified participants into three reading groups (Decoders, Balanced Readers, and Sight Readers). The reading and cognitive performance of these groups were consistent with theoretical predictions and subsequently provided external validity for the novel Reading Tendency Index classification. Our findings demonstrate a potential classification tool for readers based on individual’s developed, reading tendencies.
