Rakamların arkasındaki çalışmalar

Bu sayfada sitedeki rakamların arkasındaki çalışmalar yer alır. Bir testin sonucunuzu karşılaştırdığı her referans çalışma burada listelenir: kimlerin katıldığı, neyin ölçüldüğü, kullandığımız rakamlar ve onları denetlediğimiz sözler. Onlardan sonra Gerçekler yazılarımızın andığı çalışmalar, rekorlar ve kurallar gelir. Liste, testlerin ve yazıların kullandığı kayıtlardan üretilir; bu yüzden onlarla ayrı düşemez.

Bir çalışma bu sayfaya nasıl girer

  • Biri çalışmanın kendisini, ya da kaydı veya kuralları okur ve kullandığımız her rakamı veren sözleri aynen kopyalar.
  • Okuma günü ve okunan sayfa, sözlerle birlikte saklanır.
  • Rakamları kaynağında okunmamış bir çalışma burada gösterilmez; hiçbir test ya da sayfa da onu kullanamaz.
  • Bir çalışma eklendiğinde ya da düzeltildiğinde bu sayfa sitenin bir sonraki güncellemesiyle değişir.

Her kaydın bu sayfada kendi adresi vardır; böylece bir bağlantı doğrudan bir rakamın arkasındaki çalışmaya gidebilir.

Bir test bir çalışmayı nasıl kullanır

Bir sonucun bir çalışmayla ne kadar karşılaştırılabileceği, ikisinin ne kadar uyuştuğuna bağlıdır. Bir çalışma aynı şeyi aynı yolla ölçtüyse, sonuç çalışmadaki insanların arasına konabilir. Tarayıcı, çalışmada olmayan bir gecikme ekliyorsa karşılaştırma bir aralık olarak gösterilir. Bir çalışma yalnızca tipik bir aralık veriyorsa sonuç, o aralığın yanında işaretlerle gösterilir. Bir sitenin ya da topluluğun kendisi hakkında bildirdiği rakam, bildirildiği gibi etiketlenir ve hiçbir zaman insanlar üzerine yapılmış bir çalışma sayılmaz.

Her kayıt, kaynağın türünü söyler: hakemli bir çalışma, kaynağın kendi bildirdiği bir rakam, bir topluluk rakamı, bir rekor ya da bir yönetim kurulunun kuralları. "Akılda tutun" başlığı altında, çalışmanın size söyleyemediği şeyler sıralanır; örneğin kimlerin dışarıda kaldığı ya da yönteminin testten nasıl ayrıldığı. Ölçüm tarafı yöntem sayfasında daha ayrıntılı anlatılır.

Bir kaydı okumak

Önce yazarlar, yıl ve başlık gelir; sonra dergi ya da yayıncı ve kaynağa bir bağlantı. Rakamlar sitenin kullandıklarıdır ve çalışmanın kendi birimindedir. Sondaki alıntı okuduğumuz sözlerdir, tarih de okuduğumuz gündür. Her çalışmanın künyesi ve açıklaması yayımlandığı gibi İngilizce verilir.

    • The study measured 17.8 ms of display and mouse delay; corrected for it, the mean is 213 ms.
    • Latency rises by about 0.55 ms per year of age; the sample is not split by age here.
    • The study averaged 120 trials per person; a median of 5 trials varies more from run to run.
    • The delay window comes from two robot-timed studies of everyday devices; no study pressed a mouse, so a mouse takes the keyboard window, wide because computers differ a lot.

    Abstract: "Based on the analysis of 190 studies (18,573 participants), we estimate that the average silent reading rate for adults in English is 238 words per minute (wpm) for non-fiction and 260 wpm for fiction." and "For silent reading of English non-fiction most adults fall in the range of 175 to 300 wpm; for fiction the range is 200 to 320 wpm."

    • Volunteers who looked for a personality test online, not a random sample of a country.
    • The paper averages a domain's six facets; the test adds them up, so its figures are the paper's times six.

"Experiment 1 examined a community sample of 1469 subjects ranging in age from 18 to 65. Mean SRT latencies were short (231, 213 ms when corrected for hardware delays) and increased significantly with age (0.55 ms/year), but were unaffected by sex or education." "SDT latencies averaged 131 ms and were unaffected by age. Experiment 2 tested 189 subjects ranging in age from 18 to 82 years in a different laboratory" "age-related increases in SRT latencies are due primarily to slowed motor output."

Participants completed a computer test measuring simple reaction times to visual and auditory stimuli and choice reaction time during the ontogenetic developmental period." "Best reaction times to visual and auditory stimuli were approximately at the age of 17 years. In turn, quickest choice reaction time was approximately one year earlier in life.

    Abstract: "Based on the analysis of 190 studies (18,573 participants), we estimate that the average silent reading rate for adults in English is 238 words per minute (wpm) for non-fiction and 260 wpm for fiction. The difference can be predicted by taking into account the length of the words, with longer words in non-fiction than in fiction. The estimates are lower than the numbers often cited in scientific and popular writings." "The average oral reading rate (based on 77 studies and 5,965 participants) is 183 wpm. Reading rates are lower for children, old adults, and readers with English as second language. The reading rates are in line with maximum listening speed and do not require the assumption of reading-specific language processing." "For silent reading of English non-fiction most adults fall in the range of 175 to 300 wpm; for fiction the range is 200 to 320 wpm. Reading rates in other languages can be predicted reasonably well by taking into account the number of words these languages require to convey the same message as in English."

    Abstract: "Speed reading has been an intriguing concept for decades, at least since Evelyn Wood introduced her Reading Dynamics training program in 1959." "The research shows that there is a trade-off between speed and accuracy. It is unlikely that readers will be able to double or triple their reading speeds (e.g., from around 250 to 500-750 words per minute) while still being able to understand the text as well as if they read at normal speed. If a thorough understanding of the text is not the reader's goal, then speed reading or skimming the text will allow the reader to get through it faster with moderate comprehension. The way to maintain high comprehension and get through text faster is to practice reading and to become a more skilled language user (e.g., through increased vocabulary). This is because language skill is at the heart of reading speed." (2026-10-06, https://pubmed.ncbi.nlm.nih.gov/26769745/)

    Abstract: "adjective factors of neuroticism, extraversion, openness to experience, agreeableness-antagonism, and conscientiousness-undirectedness were identified in an analysis of 738 peer ratings of 275 adult subjects. Intraclass correlations among raters, ranging from .30 to .65, and correlations between mean peer ratings and self-reports, from .25 to .62, showed substantial cross-observer agreement on all five adjective factors."

    Abstract: "To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all." "Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40."

    Abstract: "the final sample included 62 independent effect sizes, representing more than 100,000 participants of both genders and all ages." "The average effect size was .40, indicating that 40% of individual differences in personality were due to genetic, while 60% are due to environmental influences." "study design was a significant moderator with twin studies showing higher estimates, .47, compared to family and adoption studies, .22." (2026-10-06, https://pubmed.ncbi.nlm.nih.gov/25961374/)

    Abstract: "From 152 longitudinal studies, 3,217 test-retest correlation coefficients were compiled. Meta-analytic estimates of mean population test-retest correlation coefficients showed that trait consistency increased from .31 in childhood to .54 during the college years, to .64 at age 30, and then reached a plateau around .74 between ages 50 and 70 when time interval was held constant at 6.7 years."

    Abstract: "The present study used meta-analytic techniques (number of samples = 92) to determine the patterns of mean-level change in personality traits across the life course. Results showed that people increase in measures of social dominance (a facet of extraversion), conscientiousness, and emotional stability, especially in young adulthood (age 20 to 40). In contrast, people increase on measures of social vitality (a 2nd facet of extraversion) and openness in adolescence but then decrease in both of these domains in old age. Agreeableness changed only in old age." (2026-10-06, https://pubmed.ncbi.nlm.nih.gov/16435954/)

    Abstract: "I conducted preregistered, high-powered (median N = 1,504) replications of 78 previously published trait-outcome associations. Overall, 87% of the replication attempts were statistically significant in the expected direction. The replication effects were typically 77% as strong as the corresponding original effects, which represents a significant decline in effect size."

    Abstract: "Data were provided by 267 men and 201 women ages 19 to 93. Consistent with earlier research and evaluations, there was no support for the view that the MBTI measures truly dichotomous preferences or qualitatively distinct types; instead, the instrument measures four relatively independent dimensions." "However, correlational analyses showed that the four MBTI indices did measure aspects of four of the five major dimensions of normal personality."

    Abstract: "Using the BILOG IRT program to score a sample of approximately 12,000 individuals who participated in leadership development programs, theta score distributions for the 4 dimensions of the MBTI computed using 10 (the BILOG default) versus 50 quadrature points were compared. Results indicated that past reports of bimodality were artifacts caused by BILOG's default use of a small number of quadrature points; when larger numbers of points were used, score distributions became strongly center-weighted."
