An individual picture ID with the syntactic category abbreviation (act /obj) and a unique number is given to each item. Search for Dominant names (ename)

An individual picture ID with the syntactic category abbreviation (act /obj) and a unique number is given to each item. Item numbers: from: to: (picnum)
Form class (verbs vs. nouns) - as a dichotomous independent variable, with a score of 1 for action-naming items and a score of 2 for object-naming items. Syntactic category: (pnapno)
The nine semantic categories used are: people, animals, body parts of people or animals, vehicles, foods, things to wear, small artifacts, large artifacts, and objects found in nature. Semantic category: (lexcat)
The % of responses with a valid (codable) name and usable, interpretable response times Correctness: % of valid responses min: max: (egoodrt)

Name agreement:
The number of alternative names for each picture was determined by "Number of types" (i.e., number of different names provided on valid trials, including the target name). Number of alternative names min: max: (etype)
The "H statistic" or H Stat (also called U statistic), a measure of response agreement that takes into consideration the proportion of subjects producing each alternative. An increasing H value indicates decreasing name agreement, 0 refers to perfect name agreement. H statistics min: max: (estatu)

"Lex1dom" was defined as the proportion of all valid trials (a codeable response, with a usable RT) on which participants produced the target name. Percent Name Agreement: % Lex 1dom: min: max: (elex1)
"Lex2phon" is the percent of all codable responses with a valid RT that were classified as a morphological variant of the dominant name. % Lex 2phon: min: max: (elex2)
"Lex3syn" refers to the ratio of codeable responses on which a synonym was produced. Synonyms for the target name differ from Code 2 because they do not share the word root or key portion of the target word). % Lex 3syn: min: max: (elex3)
"Lex4err" refers to the percent of all codable responses with a valid RT on which participants produced a response that failed to meet criteria for Lexical Codes 1-3. % Lex 4err: min: max: (elex4)

Reaction time:
"RT total MEAN" refers to mean reaction times across all valid trials, regardless of the content of that response. RT total MEAN: min: max: (erttot)
"RT target MEAN" refers to mean latency for dominant responses only. RT target MEAN: min: max: (erttar)
"RT Lex2phon MEAN" refers to mean latency of responses categorized as morphological variant of the dominant name "Lex2phon". RT Lex2phon MEAN: min: max: (ert2)
"RT Lex3syn MEAN" refers to mean latency of responses categorized as synonyms of the dominant response. RT Lex3syn MEAN: min: max: (ert3)
"RT Lex4err MEAN" refers to mean latency of responses categorized as error or other as compared to the dominant response "Lex4err". RT Lex4err MEAN: min: max: (ert4)

Features of the dominant response
Length in phonological syllables and in characters. Length in syllables: min: max: (esyll)  in characters: min: max: (echar)
Frequency counts were taken from the CELEX Lexical database and were Ln transformed. Ln Frequency (CELEX): (1-100) min: max: (efreq)
For our purposes here, the CDI yields a simple 3-point scale: 1 = words acquired (on average) between 8 and 16 months; 2 = words acquired (on average) between 17 and 30 months; 3 = words that are not acquired in infancy (> 30 months). Objective AOA (CDI): (1-100) min: max: (ecdi)

Presence/absence of a fricative or affricate in the initial consonant is a variable that has been reported to influence the time required for a response to register on the voice key. Initial frication: (efric)
The "shared name" variable reflects the fact that some dominant names were used for more than one picture. Items with shared name: (esames)
A dichotomous variable, 1 was assigned to any item on which the dominant response was a plural, a compound word or a periphrastic (multiword) construction. Complex words: (ecomplx)

Picture characteristics:
Estimates of objective visual complexity were obtained for the picture itself, based on the size of the digitized stimuli picture files. Obj. Vis. Complexity (KB): min: max: (ovcjpg)
Estimates of objective visual complexity were obtained for the picture itself, based on the size of the digitized stimuli picture files. Conceptual Complexity: min: max: (objnum)
