Statistical patterns in children’s early writing

Many theories of spelling development claim that before children begin to spell phonologically, their spellings are random strings of letters. We evaluated this idea by testing young children (mean age = 4 years 9 months) in Brazil and the United States and selecting a group of prephonological spellers. The spellings of this prephonological group showed a number of patterns that reflected things such as the frequencies of letters and bigrams in children’s language. The prephonological spellers in the two countries produced spellings that differed in some respects, consistent with their exposure to different written languages. We found no evidence for reportedly universal patterns in early spelling such as the idea that children write one letter for each syllable. Overall, our results reveal that early spellings that are not phonological are by no means random or universal and preserve certain patterns in the writing to which children have been exposed.     

Risky Business: Harlem Pimps’ Work Decisions and Economic Returns

ABSTRACT

In this mixed methods study of 56 entry-level pimps in Harlem, NY, we explore how pimps’ choices to use violence or control differ by where they are selling sex, who their clientele are, and whether these violent and controlling behaviors yield higher returns. First, we qualitatively explore how pimps account for each of these choices, and how each group of choices are related to the other choices. Second, we use bivariate statistical techniques to see whether there are associations in this sample between pimps’ ages and each of those decisions, and between each of those decisions and reported earnings. We find that younger pimps work with clients and sex workers in their social networks because they are easier to hold accountable, which leads younger pimps to bypass the self-reported risks involved with more violent work, but also tends be associated with lower self-reported earnings. Older pimps gravitate toward stranger clients, which involves more risk but higher earnings. Most pimps do not describe regularly using violence either against sex workers or to protect sex workers, but the use of violence is more common among older pimps. The accounts of regularly using violence with workers are not associated with higher earnings. The idea that pimps control most aspects of how sex workers labor and other aspects of their lives such as where they live are not substantiated by the accounts of the pimps themselves, but we do find older pimps describe exerting more control over sex workers than younger pimps. We discuss the implications of our findings, which demonstrate that pimps are a diverse group who see their own violence and control decisions as related to age, location, clientele, and perceived risks and rewards.     

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.     

The role of articulation in the parsing and retention of letter strings in tachistoscopic free recall

In Mewhort and Campbell's (1981) model of visual word recognition, a scan-parse mechanism transfer information from a character buffer to a short-term store and is largely responsible for the familiarity effects observed in tachistoscopic free recall. Although Mewhort and Campbell do not elaborate on the role of articulation in this task, they do suggest that the scan-parse mechanism acts prior to any involvement of articulatory processes (see Mewhort & Campbell, 1980). However, proponents of working memory (see Baddeley, 1986) are clear that articulation is necessary for the transfer of visual information to a phonological short-term store. In order to clarify the role of articulation in the parsing and retention of letter string, we asked subjects to undertake a tachistoscopic free-recall task, involving first- and fourth-order letter strings, with and without articulatory suppression and/or unattended speech. Unattended speech was observed to interfere with recall, but only when subjects were free to articulate the strings. This implies that subjects were retrieving information from the phonological store and that articulation is necessary for the registration of visual information in this store. The lack of interaction between order-of-approximation and suppression supports the view that the scan-parse mechanism acts independently of articulation. It appears, therefore, that letter strings are parsed at a stage preceding their transfer of the pharmacological store. Finally, the results indicate that subjects are able to draw directly on a representation of the parsed components of a letter string and may do so when phonological storage is difficult.(ABSTRACT TRUNCATED AT 250 WORDS)     

Compact representations of positional knowledge in short and long words for letters and features

Single-letter statistical measures providing values for each letter-position and word-length combination are too unwieldy for use in working letter-recognition models; more compact tables are needed. Compact tables collapsing word length to short or long words and letter positions to first, last, or middle letters are presented for the frequency and versatility of single letters. Letter-position and word-size differences are preserved in this reduced format. To test awareness of these values, subjects rate the commonness of letters in each letter position. Their responses indicate high intersubject agreement and correlate highly with the frequency and versatility measures. A LISP program that translates the letter knowledge for each letter into a corresponding knowledge for each feature in a feature set is described. Distinctiveness values for each feature (see Shimron & Navon, 1981) are computed.     

On the flexibility of letter position coding during lexical processing: the case of Thai

In Indo-European languages, letter position coding is particularly noisy in middle positions (e.g., judge and jugde look very similar), but not in the initial letter position (e.g., judge vs. ujdge). Here we focus on a language (Thai) which, potentially, may be more flexible with respect to letter position coding than Indo-European languages: (i) Thai is an alphabetic language which is written without spaces between words (i.e., there is a degree of ambiguity in relation to which word a given letter belongs to) and (ii) some of the vowels are misaligned (e.g., [see text] ε:bn/ is pronounced as /bε:n/), whereas others are not (e.g., [see text]/a:p/ is pronounced as /a:p/). We conducted a masked priming lexical decision experiment with 3-4 letter Thai words (with vs. without an initial misaligned vowel) in which the prime was: (i) identical to the target, (ii) a nonword generated by transposing the two initial letters of the target, or (iii) a replacement-letter control nonword. Results showed a significant masked transposed-letter priming effect in the initial letter positions, which was similar in size for words with and without an initial misaligned vowel. These findings reflect that: (i) letter position coding in Thai is very flexible and (ii) the nature of the obtained priming effects is orthographic rather than phonological.     

Evaluating Responsiveness to Intervention for English-Language Learners: A Comparison of Response Modes on Letter Naming Rates

An alternating treatments design was used to compare the effects of two response modes on acquisition and retention rates of letter naming fluency performance (LNF) by six kindergarten English Language Learners (ELLs) performing below the average letter naming level and slope of other ELL classmates. With equal amounts of practice opportunities, ELLs practiced by orally reading printed letters (see/say) or practiced by pointing to a printed letter that was orally read to them (hear/point). The see/say intervention practiced printed letter sounds to enhance oral reading competence. Alternatively, the hear/point intervention confirmed a non-verbal recognition of oral letter sounds to increase attention and information processing of oral and printed letters prior to an oral LNF assessment. The see/say intervention was moderately more effective on LNF rates than the hear/point intervention for all ELLs on the acquisition assessment and for 4 of the 6 ELLs on the retention assessment. Results are discussed in terms of efficiency as well as effectiveness when making decisions about selecting and implementing responsiveness to intervention assessments when ELLs students are not responding to an effective general education program.     

Detection of intraword and interword letter repetition: A test of the word unitization hypothesis

Do words, as familiar units or gestalts, tend to swallow up and conceal their letter components (Pillsbury, 1897)? Letters typically are detected faster and more accurately in words than in nonwords (i.e., scrambled collections of letters), and in more frequent words than in less frequent words. However, a word advantage at encoding, where the representation of the string is formed, might compensate for, and thus mask, a word disadvantage at decoding and comparison, where the component letters of the representation are accessed and compared with the target letter. To better reveal any such word disadvantage, a task was used in this study that increased the amount of letter processing. Subjects judged whether a letter was repeated within a six-letter word or a nonword (Experiment 1; intraword letter repetition) or was repeated between two adjacent unrelated six-letter words or nonwords (Experiment 2; interword letter repetition). Contrary to Pillsbury's word unitization hypothesis, both types of letter repetition (intraword and interword) were detected faster and just as accurately with words as with nonwords. In Experiment 2, however, interword letter repetition was detected less accurately on common words (but not on rare words or third-order pseudowords) than on the corresponding nonwords. Thus, although the familiar word does not deny access to its own component letters, it does make their comparison with letters from other words more difficult.     

“Just Carbon”: Ideas About Graphene Risks by Graphene Researchers and Innovation Advisors

Graphene is a nanomaterial with many promising and innovative applications, yet early studies indicate that graphene may pose risks to humans and the environment. According to ideas of responsible research and innovation, all relevant actors should strive to reduce risks related to technological innovations. Through semi-structured interviews, we investigated the idea of graphene as a risk (or not) held by two types of key actors: graphene researchers and innovation advisors at universities, where the latter are facilitating the movement of graphene from the laboratory to the marketplace. The most common idea found is that graphene is not a risk due to, e.g., low toxicity, low amounts produced/used, and its similarity to harmless materials (being “just carbon”). However, some researchers and advisors also say that graphene is a risk, e.g., under certain conditions or due to a lack of risk-related information. We explain the co-existence of these seemingly contradictory ideas through (1) the semantic ambiguity of the word risk and (2) a risk/no-risk rhetoric, where risks are mentioned rhetorically only to be disregarded as manageable or negligible. We suggest that some of the ideas held by the researchers and innovation advisors constitute a challenge to responsible research and innovation regarding graphene. At the same time, we acknowledge the dilemma that the discourse of responsible innovation creates for the actors: denying graphene risks makes them irresponsible due to a lack of risk awareness, while affirming graphene risks makes them irresponsible due to their everyday engagement in graphene development. We therefore recommend more research into what researchers and innovation advisors should do in practice in order to qualify as responsible.     

The Visual Role of Objects' Facing Surfaces

It is often assumed that when we see common opaque objects in standard light this is in virtue of seeing their facing surfaces. Here I argue that we should reject that claim. Either we don't see objects' facing surfaces, or—if we hold on to the claim that we do see such things—it is at least not in virtue of seeing them that we see common opaque objects. I end by showing how this conclusion squares both with our intuitions and with the facts of vision science.     

Self–other contingencies: Enacting social perception

Can we see the expressiveness of other people's gestures, hear the intentions in their voice, see the emotions in their posture? Traditional theories of social cognition still say we cannot because intentions and emotions for them are hidden away inside and we do not have direct access to them. Enactive theories still have no idea because they have so far mainly focused on perception of our physical world. We surmise, however, that the latter hold promise since, in trying to understand cognition, enactive theory focuses on the embodied engagements of a cognizer with his world. In this paper, we attempt an answer for the question What is social perception in an enactive account? In enaction, perception is conceived as a skill, crucially involving action (perception is action and action is perception), an ability to work successfully within the set of regularities, or contingencies that characterize a given domain. If this is the case, then social perception should be a social skill. Having thus transformed the question of what social perception is into that of what social skill is, we examine the concept of social contingencies and the manner in which social skills structure—both constrain and empower—social interaction. Some of the implications of our account for how social and physical perception differ, the role of embodiment in social interaction and the distinction between our approach and other social contingency theories are also addressed.     

Employer Preferences for the Form and Substance of Employment Application Cover Letters

This study investigates the effect some principal characteristics of employment application cover letters have on personnel officers. A sample of personnel executives from 100 major companies was queried as to their perception of the desirability of 12 common cover letter characteristics. The results indicate that the personnel officers do not consistently perceive letters in the manner suggested by the existing literature. Some characteristics are shown to elicit negative responses from personnel officers, and thus should be avoided by job applicants. Several characteristics are strongly preferred by the sample surveyed. The model for an employment cover letter derived from this study should enhance the applicant's chances for a favorable response, or at least prevent letter forms which might detract therefrom.     

Word-based grouping affects the prime-task effect on semantic priming

Semantic priming between words is reduced or eliminated if a low-level task such as letter search is performed on the prime word (the prime task effect), a finding used to question the automaticity of semantic processing of words. This idea is critically examined in 3 experiments with a new design that allows the search target to occur both inside and outside the prime word. The new design produces the prime task effect (Experiment 1) but shows semantic negative priming when the target letter occurs outside the prime word (Experiments 2 and 3). It is proposed that semantic activation and priming are dissociable and that inhibition and word-based grouping are responsible for reduction of semantic priming in the prime task effect.     

The influence of multiple readings on the missing-letter effect revisited

In searching for a target letter while reading, participants make more omissions when the target letter is embedded in frequent function words than when it is embedded in less frequent content words. According to the guidance-organization (GO) model, this occurs because high-frequency function words are processed faster than low-frequency content words, leaving less time available for letter processing. We tested this hypothesis in three experiments by increasing word-processing speed through text repetition, which should translate into higher omission rates. Participants either read the text and searched for the target letter once or read the text three times and searched for a target letter on all readings or the final reading only. In all the experiments in which participants could not anticipate the target letter to be used, results revealed the presence of a large missing-letter effect that was unaffected by familiarity with the text. In addition, when participants knew from the start the target letter to be used on the final reading, the missing-letter effect was eliminated. Repeated search of the same text for different targets increased omissions equally for function words and content words, but this finding was present even when a new text was used, suggesting that repetition of the search task, rather than familiarity with the text, was responsible.     

How residents cope with living near a hazardous waste landfill: An example of substantive theorizing

It is hard to be a community or environmental psychologist and not be interested in newspaper stories on global warming, oil spills, or toxic wastes in your own backyard. To the general public, these issues tend to be viewed as environmental, technological, toxicological, or governmental, but not psychological. As psychologists, we see many ways in which psychology does play a role in understanding these events. We have been engaged in a study of residents living near a hazardous waste landfill in which many subdisciplines of psychology have played an illuminating role. Wicker's (this issue) article on substantive theorizing outlines an approach to theory and research that helps communicate the structure and process of doing research on a complex area. We use his article to help us describe key aspects of our research that are not usually discussed in research articles. We believe that the type of research Wicker describes occurs more often than people realize. Unfortunately, however, journal conventions cause investigators to omit discussions of substantive theorizing aspects of their work. We hope that reading this article increases your understanding of substantive theorizing and our research as much as writing it increased our own.     

Rotating With Rotated Text: A Natural Behavior Approach to Investigating Cognitive Offloading

Determining how we use our body to support cognition represents an important part of understanding the embodied and embedded nature of cognition. In the present investigation, we pursue this question in the context of a common perceptual task. Specifically, we report a series of experiments investigating head tilt (i.e., external normalization) as a strategy in letter naming and reading stimuli that are upright or rotated. We demonstrate that the frequency of this natural behavior is modulated by the cost of stimulus rotation on performance. In addition, we demonstrate that external normalization can benefit performance. All of the results are consistent with the notion that external normalization represents a form of cognitive offloading and that effort is an important factor in the decision to adopt an internal or external strategy.     

Encoding speed of visual features and the occurrence of illusory conjunctions

Earlier studies have found that people show characteristic errors when asked to observe a rapid stream of events and to name the colour of a certain letter, or the letter in a certain colour. They tend to report the letter or colour from an event later in time than the correct one. This is not true, however, if they are asked to name the colour of a digit amongst letters, without knowing in advance the identity of the digit. There is also some evidence that the errors are symmetric if the location of the target is not known in advance. Three experiments are reported which show that this symmetry results from slow encoding of the colour as compared with the digit. It is still true that uncertainty about target identity does reduce the tendency to see the target in a later than an earlier colour. This effect is, however, superimposed on asymmetries resulting from coding speed, and the effect of uncertainty of location may be due only to this.     

Assessing the importance of letter pairs in reading-parafoveal processing is not the only view: reply to Inhoff, Radach, Eiter, and Skelly (2003)

D. Briihl and A. W. Inhoff (1995; see record 1995-20036-001) found that exterior letter pairs showed no privileged status in reading when letter pairs were presented as parafoveal primes. However, T. R. Jordan, S. M. Thomas, G. R. Patching, and K. C. Scott-Brown (2003; see record 2003-07955-013) used a paradigm that (a) allowed letter pairs to exert influence at any point in the reading process, (b) overcame problems with the stimulus manipulations used by Briihl and Inhoff (1995), and (c) revealed a privileged status for exterior letter pairs in reading. A. W. Inhoff, R. Radach, B. M. Eiter, and M. Skelly (2003; see record 2003-07955-014) made a number of claims about the Jordan, Thomas, et al. study, most of which focus on parafoveal processing. This article addresses these claims and points out that although studies that use parafoveal previews provide an important contribution, other techniques and paradigms are required to reveal the full role of letter pairs in reading.     

Case-sensitive letter and bigram frequency counts from large-scale English corpora.

We tabulated upper- and lowercase letter frequency using several large-scale English corpora (approximately 183 million words in total). The results indicate that the relative frequencies for upper- and lowercase letters are not equivalent. We report a letter-naming experiment in which uppercase frequency predicted response time to uppercase letters better than did lowercase frequency. Tables of case-sensitive letter and bigram frequency are provided, including common nonalphabetic characters. Because subjects are sensitive to frequency relationships among letters, we recommend that experimenters use case-sensitive counts when constructing stimuli from letters.
